IBM was porting AIX to Intel for Itanium back in 2000-2001 (Project Monterey), but delays in the chip release got IBM to shelve the project. One of the challenges was making the code "endian-neutral" since x86 is little-endian but PPC is big-endian. In theory, AIX could now be built for Intel platforms fairly easily, but IBM has little reason to do so. It's not out of the question but there's been no stated intent.

Actually, AIXv3 had an Intel version, if you can find a copy! I bet that would run in a VMWare appliance, too. But sheez that is old...1995 I think.
