Should really include Frank Castle
He's worked alongside virtually everyone here at some point or another including the Marvel Knights series (Which was okay...). He's also "romanced" Elektra more than a few times. The guy isn't a team-player but he is the greatest tactician (By far) in any of the line-up and he's on-par with guys like Batman and Captain America when he's at his absolute best and no longer in "year one" mode.
Edit: I may have a bias cuz eyepatch-wearing solidarity but I want a NON-FORCED Nick Fury inclusion. Fury isn't retired unless things in CW change that status. He would want to closely watch a group of people with guys like Luke Cage and Jessica Jones in the mix, he could also have a past with Frank Castle or some kind of tie-in. We know that this Frank has done some high-level black ops stuff.
