I would imagine a Heroes For Hire show would likely start with them separated doing their own things and then merge them together. For better or for worse, what they did in Defenders would be an example. That being said, Season Two played with the Hero for Hire idea and ultimately went away from it. It feels a bit like backtracking to now go there. A Power Man and Iron Fist show (likely not with that title) feels more likely than actually making them heroes for hire.
