There is no point in going over to X86. The point that would have been sensible is long long gone. It might have worked when comodore were still around.
These days what would be the point, and before you say cheap hardware, that is not enough.
It would take a massive amount of work to port and then you would have to run all the old applications in an emualtion, like you do now on the ppc. So what would be the point just use winuae.
OS4 or MorphOS just do not offer enough against linux, macOsx and windows.
MorphsOS and I assume OS4(not tried it , as there is no way to try OS4 without buying) are ok for a hobby next gen Amiga OS on PPC hardware.
