What if...the Avengers Grew Up Together?

This has just been something that's been bouncing aroundy head since it premiered in season 2. It's a continuation of episode 2, "What if...Peter Quill Attacked Earth's Mightiest Heroes?" My thinking is that with the Avengers basically being formed early, Tony Stark probably grew up with Peter Quill, Hope Van Dyne, and probably T'Challa and Shuri. Thor, a Thor that never had to learn to be worthy mind you, would probably be their crazy uncle. Carol might not have become Captain Marvel. Bucky would probably be like the Batman of Brooklyn, maybe even becoming a mentor to Spider-Man when he makes his debut, or the Defenders, hell even help Frank Castle/Punisher come to terms with things. That honestly feels like a What If...? all on its own.
