Dennis's minimig recreated the Amiga 500 and I thought the Natami boys were going to do an Amiga 4000+ clone-except the urge to shovel in all the features of computers developed post Commodore has really slowed the progress.
There can be such a thing as "biting off more than you can chew";I .too, have started things beyond my ability and resources,ultimately having only a learning experience as the result.
Acube with the SAM has staked out the post-Commodore hardware for now,and without comparable or better backing ,I doubt Natami can even match that ,much less surpass it.
But I also think a Natami that consisting of a basic A4000 class CPU and video with plenty of board slots for Zorro and PCI(e) cards should have been the first project.Sort of like the Elbox Dragon? that never made it.
