You should probably stay with emulation.
Personally, I have a couple of legacy systems for Amiga software.
But the latest emulators do a great job of running legacy software with what ever hardware you would like to be emulated.

I am relatively sure that most of us are ready to jetison legacy compatibility.
After all, old Amiga software is just that...old (and pretty obsolete).

So what is likely to move to X86 is the best features that MorphOS has (enhanced without the constraints that legacy compatibility requires), not necessarily features of AmigaOS.
