Star Wars Connection?
Okay so hear me out...(ducks tomato)....no wait a second:
Now that Disney owns both Marvel and Star Wars would it not be pretty cool if they had some level of connection between the two properties? I think it would be very cool if it were done on a very peripheral level.
For example what if Episodes 7-9 (which remember take place in our universe, only a long time ago in a galaxy far, far away..) deal with an enemy creating some kind of super powerful "force" weapon and it's fueled by (what is later called thousands of years later when they are rediscovered in a distant galaxy) the Infinity Gems.
That could be a small little nod to something much larger in the MCU without having a direct crossover. It certainly expands both universes into something much larger and deeper. I think it'd be cool but then again I'm from the east coast and I only just got my power back...so maybe I've been driven completely insane. Whichever.
