That would be interesting, but I don't see how they can fix the inconsistency of Oscorp and Avengers Tower not being present previously. The only way it can work is if the ASM movies take place before the avengers since I see oscorp tower being taken down long before I see Avengers tower being destroyed.
EDIT: Then again maybe Avengers Tower can be destroyed. idk, I just see Oscorp as a gigantic building that's ultra tall compared to avengers tower atm. You simply can't miss a shot of that building if the cameras up in the sky.
New York is a big city. Even then it'll never happen.
We'll never see a true encompassing marvel universe.
