^But you'd need to address all the Avengers' reaction to it. I mean Tony and Cap were already having reservations about working with SHIELD after what they discovered, it's going to be a major betrayal if they find out Fury used Coulson's death to manipulate them.
I think the future movies will head towards the avengers not accepting SHIELD and doing their own thing
Captain America 2 has Cap wear a SHIELD issued version of his suit. Apparently he won't like it and goes to his old WWII suit or a mix of old and new.
