None of the PC-FXGA discs work in a regular PC-FX, so unless you had a working PC-FXGA in your machine and could burn the FXGA CDs correctly, it wouldn't work.
...in addition, the games/demos could be compiled to play in a PC-FX, however this probably won't even begin to happen until the FXer is completed as we are still discovering how the FX works.
Lastly, I believe you are right about the tech school. There is a Japanese site that I've seen that has FXGA demos and projects, but I don't have the link at the moment...you might want to search google for "PC-FXGA" (make sure you choose Japanese as the language). Aaron Nanto
