Replies have been very off topic since the start, so I guess that this is of no interest. But let me attempt to bring it up again...
I assume that, given the proper, merely administrative, conditions, a new Amiga home computer could be built, based in the Efika. So, giving lawsuit for granted (ahem), hardware is no problem: It would be the standard board with the soldered video chip (by the way, does the Efika have onboard sound?).
So the problem is, again, system and applications software: In order to be an Amiga, it should run an Amiga like operating system (MorphOS, of course). As for the main applications (you know: games), UAE could come in handy. Any estimations about how nicely would this emulator work in this 400 Mhz 603 core?
All in all: Would this product be technically viable? I think that the commercial aspect could be guaranteed, look at the sales of the C64 DTV.
