There is no way a marvel gaming universe would succeed. Not because the idea isn't want the consumers would want. But because actually managing it and developing it would be impossible if you want the standard to be as high as it is with the current Spiderman
Games get delayed, a lot. Specially single player games. Their development can go to shame fast and things can get off track easily. It's not like movies were production is much faster and it takes 2 years to get a movie out. Were talking 4~ years per game.
So setting a coherent story and events in a large universe accross multiple games, with multiple studios, would be a nightmare. Plus keeping up with the same chain of events will create huge creative conflict.
