Why not? Then well have the Mickey, Bugs Bunny, and Muppets Crossover Cinematic Universe that I dont think planet Earth is ready for.
I don't think so. I can see Disney buying some assets from Comcast / Time Warner, but the whole of Warner Brothers? I doubt it.
They can, but WB won't let em.
They have the money to make it happen, but WB has an equally successful history as Disney and I'm doubtful they'll shit on it via a buyout.
