Are you talking about designing your own system? If so, you should just use the MiniMig, and call the SD memory a "cartridge". This would give you a cartridge based game console with specs almost identical to a NeoGeo. If you want a more "cartridgy" feel, then replace the SD cards with Compact Flash.
If you want a really powerful console, forget the Minimig and go with either the
Natami with its SuperAGA chipset or, if you don't mind running your Amiga stuff in an emulator, the
Pandora hand-held will be a welcome addition to any developer's toybox.
Note: Both are close to being released so it's probably not worth starting over from scratch just to find somebody else is doing what you wanted to do.
