I don't know if any MJs did, but I have seen several XJs with AW4 and 4 cyl. One of the trans is sitting in a junkyard in Bellingham, WA, but they think it is solid gold plated or it would've gone into my '86 4 cyl Comanche!
The flexplate is different than the 904 one. The 4 cyl got MPFI late in '90 and those are the only ones I saw with the AW4. It uses the same throttle body as the later TJs and CPS as the 4.0L. Wish I'd had my camera with me the last time I saw one of these rigs!
