Nice, but TV has already been doing their versions of inter-universe cross-overs and spin-offs.
One aspect television-wise that I think is interesting -- how would connecting universes affect a series that's on it's way to cancellation? Example - I don't regularly watch Syfy shows, but I'm aware that Eureka and Warehouse 13 had cross-overs and basically established themselves as sharing the same universe. Then they went a step further and subtly introduced a character from Warehouse in the newer show Alphas, connecting all three shows. Right now, Eureka is slated for cancellation while the others have been renewed. Would it make sense to just throw out that connection and content? Hell, two characters apparently fell in love in one cross-over; is that getting glossed over? More importantly, with shows like Family Guy and Futurama being brought back by fan demand, could featuring a recurring character from a canceled series have the same outcome?
