To be honest, I would not have had Red Hulk on the team right away. If I were in charge, Red Hulk would not be on the team until mid-season. For the first several episodes, I'd still have Red Hulk be General Ross, trying to discredit and destroy the Hulks, perhaps against orders. Eventually this bites Ross in the ass and he turns (permanently) into Red Hulk. After a few episodes of him being an enemy to EVERYBODY, he has no choice but to begrudgingly join the SMASH unit by mid-season. My initial team probably would have been Banner/Hulk, Jen/She-Hulk, Lyra (following my scenario), Rick Jones (who is still human for now), Doc Samson, and Skaar (whose motivations would be a complete mystery), but Doc Samson's ties to the military are strong. In fact, that's probably how Ross' final battle as a human being is fought. The SMASH team is probably too roguish for Samson, so he reaches out to both SHIELD and the military for legitimacy, and Ross accepts Samson's overtures, but only to lure the SMASH team into a trap and destroy them. Needless to say, this fails, Samson is discredited (though this wasn't entirely his fault), and Ross gets turned into Red Hulk and has his own troops firing upon him. Samson winds up being brought into SHIELD, and Betty joins the SMASH team though she is still a normal human being. The SMASH team would be in disarray for a bit, as Banner/Hulk views what Samson did as a betrayal. Banner and Samson's relationship would take the rest of the season, if not into Season 2, to mend. Along the way, the SMASH team would eventually recruit Red Hulk (who's doing this mostly out of concern for Betty) and Delilah Dearborn/Geiger (who I have aged up into a thirty-something mother of two and "locked" into her Doc Samson-esque strength and appearance) by the season finale. Rick and Betty would not transform until season 2.
God, I'm rambling again. I'll stop, promise =3
