Emulation IS possible. Some users with patience and skills enough have already tweaked a version of QEMU (
http://wiki.qemu.org) to run it.
PearPC should also be easy to tweak in order to run AOS.
The problem is that no one would give you (or me) that version of QEMU, and if you're crazy enough to code it by yourself, you'll be crucified by several users only by telling the community you have it.
The best way to try something Amiga-like (IMHO) is to buy a 2nd hand Powerbook G4 and wait for the release of MorphOS 3d and internal wireless drivers...
