Well, if you were to obtain the Colecovision "rights" you then own the original code, and would need to re-license certain arcade titles if necessary. It was done for the CV Flashback, after all. The problem is that Coleco is part of Mark Thomann's Dormitus Brands, and he's actively been producing retro product under the Coleco banner. Albeit not much actual Colecovision material, but their business is basically the same as Atari S.A.'s so I'm not sure they're interested in selling.
