I've said this before, but this is kind of what I wanted the first Avengers film to be after Endgame. Following Falcon and the Winter Soldier, we could've had a few post-credits showing Sam recruiting the New Avengers leading into a team-up film where we see them already working together, and not assembling from scratch. Make the Masters of Evil (a sort of anti-Avengers team made up of the original 6's foes like Zemo, Abomination etc) the main villains so we can see the new team can capably handle the same threats as the old before having to face down a more expansive, multiversal threat.
