Sure it can be done. Someone did it once with a p5, i think it went something like this:
He had to run like 3 computers or something... the p5 computer, one for the kj, and i think the kj's auto transmission computer (the kj was hooked up to a standard trans, but the auto trans computer is needed so the supercharger will boost normally). After the wiring/computer mess was sort of fixed (i don't know if he ever got it working 100%... he was able to drive it around though) the supercharger blew and he abandoned the project.
The KJ's not worth it- nothin' wrong with the regular ole' KL swap though
