The danger with adding more Avengers is falling into the "double the characters for the second film" trap. Just so easy for it to turn into a mess, unless they take away someone from the cast of the first film. With Cap, Hulk, Iron Man, and Thor more or less unmovable, the sacrifices would have to be Black Widow and/or Hawkeye, and yet, Widow is amazing, and Clint is cool in his own way. Now, Whedon is good at juggling characters and keeping them all "alive" for us, but I'm also remembering how Buffy tended to err in overexpanding its cast, which cost it in charm and sense of intimacy. Over there, it happened over seven seasons and I don't know how many episodes, but in Avengers, it would be sudden. If Antman and Wasp were introduced through Iron Man and Black Panther through Captain America, not everyone would have to be in the next film itself, but we'd still get to see them. For example, War Machine in Iron Man 2 was all that was needed.
