This idea seems poorly thought out. Think about it: For every series included, you would have to divide screen time for.

For the same reason why Doctor Who has never attempted more than four doctors in a crossover at once (as main characters, anyway), a full wiki wide crossover just wouldn't work. You're dividing time and attention between characters of equal importance. And if everyone is a main character, no one is.

Say someone, for some reason, hated Generator Rex. Heroes United is still a good watch for them, because it's still 50% Ben 10. However the more series you add in, the less Ben 10 it becomes. Add in enough series, and eventually you lose all identity it once had. same applies here.
