Gyroglider

I would say no. It will be impossible to get bearings for the rotor that can turn easy enough and avoid running hot or seizing up. Plus the problems with the glider.

Fixed-Wing Glider

It will be problematic to get the structure strong enough and light enough at the same time. Getting materials for the wings will difficult, too. Imported bamboo and silk?

The next problem are the control surfaces. That could be overcome with a basic hang glider, but for anything larger than that you probably need steel wires (and bearings, again).
