Nice
I think that hank is gonna get chucked out (maybe he's the source of the leak?) and thinks "hey, I don't need those clowns." And then bumps into hellstorm doing a kids birthday party and hires him
Thus the idea is born. Ok, the first part of that is what I think. Though why would Pym do such a thing as he and banner have seemingly got over their enmity, unless it's all a ploy on Pym's part to mark him seem less of a suspect. That's an issue for another thread though I'm sure.
ok, the characters, I already mentioned Valkyrie.
Luke Cage can easily be a mutant, hell, even just a tough guy. I don't think they need to alter much about him. There will be some personality tweaks I'm sure, but I could only guess at these. And I think it would be interesting (but not right), if they made him a bit of a wimp, he's a big tough guy, really strong, but a complete pussy when it came to the crunch. I guess it depends on how much fun you wanna have with the character. Like I said, I don't think this is right, but it would be fun.
Hellcat I'm seeing as just some supercool athelete, kinda like the black cat. Personality wise - we can say catty with some ease I think. Though not to the hilarious Black widows levels
NIghtwing, well.. I dunno actually. He's a guy in a dumb suit that is gonna mocked somewhat for that. for sure.
And hellstorm, this is the tricky one too. Maybe he was just a street performer. Smoke and mirrors my friends. Who's to say.
