If there is a chance that the original six cast who was the avengers, and that they would be villains, why not make them the dark avengers? Except the team wouldn't have the original comic book line up, but the team would have superior iron man aka tony stark, captain hydra aka steve rogers, ragnarok the thor clone, maestro aka bruce banner, yellowjacket aka hank pym, and red queen aka hope pym. Plus, they could be led by kang the conqueror as a alternate earth's evil version of avengers.
