7. Dark Reign

They almost definitely won't do this, but it would be interesting to see them try.

Spinning out of Secret Invasion, the keys to SHIELD are handed over to the man who comes out of nowhere to save the day: Norman Osborn, aka the Green Goblin. We haven't seen the MCU’s Norman Osborn yet, but I think introducing him as SHIELD's new director would be a dramatic change of pace.

HYDRA secretly perverted and weaponized SHIELD in Winter Soldier, but in this case, someone would very publicly take a governmental body down some extremely dark paths. This would give us an excuse to make Spider-Man a main Avenger, and that would set him up to take down Norman Osborn's Green Goblin in his own movie.

An evil businessman who corrupts a government force to make an illicit profit? I can see that resonating with some people.
