There are many things wrong here, which is probably why you aren't getting any responses.
First, find a AX15. Hopefully later than 94, so it has the external slave. Otherwise, you'll be trying to hack the CPS onto the old transmission bell housing. Yes, it's possible, if you have a machine shop available.
Second, you can't use the 4.2 flywheel and PP. The flywheel must match whatever ECU that you are using - I'm assuming 94 XJ 4.0L ECU? So you need a 91-98 flywheel, pressure plate and clutch.
Third, you really need to do a bunch more research.
There's wiring details, ECU details, transfer case input gear lengths and spline counts, and I'm not sure that you have taken all these things into account.
Research, research, research...
