Hyperion just isn't interested in porting AmigaOS onto a cheap, mass market hardware solution.
AROS on ARM is the best option, with a 68k emulator for native app compatibility (hopefully still calling the native AROS libs, like OS4's Petunia emulator).
An FPGA for native hardware compatibility is a nice thought, but would turn the hardware from cheap commodity into bespoke expensive. So a perfect match for this community.
