Since I own a 323 GTX (AWD...that my buddy wrecked), I seriously considered it. My opinion is similar to those who have already considered it. It's not worth the trouble, unless you're a lottery winner. Of course it can be done, and probably easier with a BP motor (1.8) but possibly with the FS motor, but I could take my Trans Am to 1000 whp for the money it would take to pull off the swap, which would be infinitely more fun.
If I were to do it, I'd go for RWD only. The AWD Protege or maybe a 323 GTX would come into play for donor parts, and a shitload of work would follow. If you want to be the first, have at it!
