Selling the hardware would be fine, but the user would have to manually download the ROM from and load it (which if there's a nice interface to do it, shouldn't be a problem for a person that thinks in RPL).

We went through something like that many years ago with hpgcc3. We provided a "patching" program that would modify the 50g ROM provided by the user to install hpgcc3, this was required to properly execute "ARMCode" objects. We could not distribute an already modified ROM (and we aren't even talking of selling anything, that was simply redistribution), and this became an obstacle for adoption.

This new 48 recreation project would have to do something similar to "expand" the 48 with special opcodes or ROM patches. From the emulation layer you can provide virtual Saturn opcodes, but if the ROM doesn't use them there's no advantage, so the original ROM would definitely need modifications.
If you wanted more RAM, I wouldn't even know where to begin to expand the Saturn memory addressing system, that would be a very difficult thing to do.
