Re: MCU-ize Marvel Characters
I would take the FF and craft more of an adventure series out of it, like an Indiana Jones type feel with the group going after crazy artifacts and exploring other dimensions. In an opening action scene I would introduce AIM to the MCU as they try to intercept the FF's discovery of some powerful object. And no origin film, I would have a whole thing where the Baxter Building is like a tourist attraction (the FF being huge celebrities in this world) and the origin is told in a Jurassic Park style ride/video.
