How about no. First of all it makes no business sense to build up these individual IPs and then just combine them into one show (especially when Defenders will be that team and Marvel probably wants to play the long-term game with these characters by turning them into actual TV franchises). In universe, we don't really know if the whole H4H concept can even work because outside of Jones, we don't know if these characters do work for hire heroics and if that matches the character arcs set up. And lastly, I don't want to give up Luke Cage and Iron Fist solo series just for that. Both have extensive histories of their own that can allow them to sustain their own series for long. I'd like characters popping up in each other's shows, but I'm not for cutting some of these shows away.
