It would take a lot of work, and gas mileage would be worse, reliability would be worse, but yes, it has been done.
Unfortunately, a 1997 Toyota Supra engine and trans would not fit into a 1990 Mazda Miata. The Supra engine and transmission are unable to be mounted correctly within a Miata to make them fit.
Will a 1992 mazda miata hardtop fit a 2000 mazda miata?
NO

Should, I believe you will have to switch the seat frames though
No, the miata is rwd, the capri is fwd.
Many different engines can fit into the Miata. See the link below to Flyin' Miata, a company that does such engine repalcements.
Yes. If you have an RX7, then it already has a rotary...and if it is a 1997 then you have a rare Japanese model.
It fits a 2002 Mazda Miata; 4 cylinder
www.gomiata.com sells custom-made Mazda Miata glass parts which you can fit in at home and is fairly cheap. It is also very easy to put into your car once it is delivered to you.
I just put a top and frame from a 1999 miata on my wifes 1996. Easy to do and you get a glass back window.
