Build the Amiga on a joystick, add in the top 50 games and/or a way to import them off of SD memory card and yeah, it'd sell a few hundred thousand at best, but that's still not enough, because it's sales/impact would be a short-lived event and there's not much to follow that up with...
Well, an Amiga in a joystick is a quick and cheap way to start to make some money, and show there is an Amiga company at least doing "something". The hardware has already been reimplemented with the minimig. Some companiess already released some of their game on backtoroots. So the "only" thing needed would be to make the minimig smaller and possibly within only a single ship, design a joystick, contact some companies to have a dozen of games, build, produce and distribute it.
That would be a good start... That's the first thing, with the release of 1.x roms for free, I'd do.
Since there is no money to make, nor to found the development of the OS, open sourcing what can be would be a good idea.
Whatever happens, "open" must be the word... Everything gone so bad because people and/or technology have been so closed for the last decades... no cooperation, closed source, wars,..
