RTD did consider turning the Star Trek crossover idea into a sort of Star Trek Lite. The Doctor would end up aboard a starship very similar to a Starfleet ship with the crew being comprised of Star Trek archetypes. IE, Captain, XO, science officer, medical officer, engineer, token alien officer. The Doctor would even express doubt at what he viewed as an "obvious military organization" claiming to be peaceful explorers. I guess it's an idea RTD might theoretically get to these now, though these days it might also be viewed as being too similar to The Orville or whatever Black Mirror's Star Trek parody was.
