Ummm… No.
You cannot get a wingspan that small to lift a man.
Graphine is a super conductor, highly efficient only when it is in compact, single atomic layers. There simply isn’t a cost effective way to collect that much carbonado. Its not even known if its native to earth, or comes from a meteorite that struck Pangea… and furthermore, is a silly expensive substance to pick, and has no especially important properties to it for lifting a man.
Your choice of engines suck too.
Your engine… its not so much it’s weight to power, like with propeller-fixed wing.
Your trying to go small in aspect, but the aspect effects the entirety. So the entirety holds play holistically in every aspect.
Foucault’s Pendulum, Paratrooper in a Parachute, Spider on a Gossemer.
Its long and slinder, with a compact center of gravity, able to take the woof and warp of the forces against it for movement, and exploit the slightest surge of force against it to multiply its dynamic momentum.
So… What if we made a engine very small, but it’s fuel source built into a H-Harness capable of holding a man? A engine small enough to fit on a T-10 Delta reserve parachute?

This is a H Harness with the reserve chute:

The reserve chute in front, main chute in back, all attached to the H Harness, person inside

H Harness is the lightest, minimalist platform for lifting a man for a extended period of time in air. Front reserve chute is expendable.
Now, we have a sport called power paragliding. The engine is rear mounted, with the propeller:

Propeller is often made of wood, with a simple, light engine attached, nothing of the caliber your talking about. Propeller is often fiberglass or wood. Simple to make.
Parachutes vary, but you can use stock surplus military parachutes, and modify cells in the parachute to allow airflow.
Now… you want a dainty engine to lift a man, devices designed to operate within Bernoulli’s Principles of flight.
en.m.wikipedia.org/wiki/Bernoulli’s_principle
How you get a heavy ass man in the air using less capacity to grab air via the engine is to substantially offset the static deferentials of it’s none powered elements, so they exploit scalar movement.
An example being, say I had a open parachute open, hooked up to me, but it was flat on the ground, away from the wind. If I picked the bottom up, and flicked it, parachute would open, and the chute could catch the scalar wind, and I may very well find myself gliding (or being ruthlessly dragged downhill to my death).
A very minor movement, a flick of my arms.
A parachute has guiding risers, the H Harness has 4, two front, two rear, coming off the shoulders:


Its the four lighter green cords coming off the top, with pieces of 550 Cord still attached (550 cord is a expensive, high tensil military string that is also marketed to the public).
The idea of maneuvering a parachute via the risers is equal to how sailing ships used to egg the currents, sail would be directed towards wind, and if not hitting directly to thevrear of ship, energy would be pushed down, and ship would Bob at a angle, while steering into the water, forcing it foreword.
A parachuter pulls on the riser, and that part is pushed down along the circumference of the parachute, shooting air out the opposite direction, acting like a thruster. However, the parachute falls faster as a result, as it has less air trapped beneath it, making for a more painful, if not hazardous landing.
If you have a small engine mounted in front of the H Harness, and decide to have the rear parachute back mounted, or your tiny as fuck device in the rear, throwing the parachute up, its all unlikely to work. However, if we know it is all about getting the chute up in the air, catching a current and taking off, then you may be able to make some compromises.
- Your tiny wings pump helium or explosive hydrogen into a fat ring around the chute, within flexible piping. Basically a mini Zeppelin. Lame, but can be done.
Attennas coming off the back of the H Harness expands the parachute, and using reflexive algorithms, continuously adapts the parachutes front and center to gain maximum air resistence, and man eventually putters off if enough wind comes along. Your little birds power the movement of the long antenna via servos. This could be done, especially for a little woman on a very hot day, as heat rises.
Third possibility is the gossamer-pendulum effect. Using hidden forces usually not considered, maximizing the weak and strong nuclear forces… long, skinny tublers of nano-fibers, comprising of carbon nanotubes with carcon buckeyballs as joins and ampliphiers. The parachute could be powered by simple seismic minutia, like sound even, how sensitive it would be. Can’t be built yet, stupid expensive and low industrial yield of both kinds of nanotubes to laboratories.
Or, just use a normal propeller, and a normal parasailing propeller, and have fun.
The engine design, if front mounted, can exploit Foucault’s pendulem… think of a doughnut shape, fueled by its own crankshaft in a downward motion, downward and upward tubes along the front H Harness, up to the parachute, to the top if necessary. Air cooled on the way up, energized in the canopy via chemical reaction to air and sun, and dipped back into the doughnut engine. Possible static electricity possibilities here too.
Bernoulli’s principles significantly limit the effective use of very small devices. Not theoretically impossible for a very small ramjet. Normal ramjets only operate at very high speeds. Fastest I’ve ever gone is a 130 knots. But there might be smaller ranges your device could exploit to get minimum thrust to get a chute up without weird tricks.
How normal people do it:

She’s a lady… (your propellers on that tiny dragonfly would be well passing the sound barrier, far faster than your carbons could take, to lift her petite ass this high. More likely to catch her on fire or tunnel through her, and break every window in a several mile area around the failed liftoff resulting in the worst suicide ever recorded in history).
From the authority of a former arctic paratrooper who grew up on Beale Air Force Base, California and knew SR-71 Blackbird pilots.

Now skynet has yet another reason to hunt my ass down.
