I was thinking about who might be able to fill Dr. Strange's spot in NA. I changed my mind given the fact that he is unregistered and think it would be cool for the new Captain America to join. He has a history with Wolverine, which is interesting and it would just seem like a better fit for him, rather than putting him in Mighty Avengers. The NA was largly loyal to the first Cap to begin with. It makes more sense.
I'd like to see Thor on the team also, but he wouldn't show up every issue. He could give them sanctuary in the new Asgard when they need it. He would fill the powerhouse position nicely and be a great opposition to the Sentry in MA.
I'd like Clint to be Hawkeye again, now that Iron Man knows he is back.
Maybe Marvel Boy could make his big return and become part of the NA under the guise of Ronin, seeing as how he was a fugitive at one time, having declared war on America. After his chat with the Illuminati, he becomes a hero for a change and sides with the Avengers.
Tigra would make sense given her recent problems with The Hood. Maybe she gets fed up with the registration as a result and begins aiding the NA. Everyone says Bendis doesn't like her, but he seems to be using her alot lately, and she does put up a fight by the end of last story arc.
1) Captain America
3) Luke Cage
7) Iron Fist
9) Marvel Boy as Ronin III
Back when we were all guessing who Ronin was, I thought NohVarr was a possible candidate. Obviously he wasn't and has hardly been used since. So, yes I'm going to include MarvelBoy as Ronin in this line-up.
2) Winter Soldier-Cap
3) Marvel Boy as Ronin III
6) Jocasta=-Offline and Anti-Stark
7) Gilgamesh-Back from Limbo
8) Songbird-Finally on the right side
