You could check out the A500 mini, more of an emulator though - https://retrogames.biz/products/thea500-mini/
The software it uses, amiberry, is open source and was made for the more powerful, useful and common Raspberry Pi boards. Getting one of these is a much better idea.
I wish someone would make an Amiga shell for a Raspberry Pi that's quality like that. I can 3D print my own, but injection molded plastic is still a quality level above.
