NN are _just_ transfer functions. Look up tables. Or really dense maps. So f(g(x)) make total sense. But I dont think these are the interesting combinations. I think giving one NN the training experience of another, plus the feedback on "correct inference" will be when on NN trains its replacement.

Yes, of course. f(g(x)) was the simplest possible example I could come up with to illustrate the point :-)
