I agree with Sophie, the Avengers universe has already been established so to try and fit the X-Men into that would be a mistake on Feige’s part. What he should do is set up the mutant-verse first, tell the X-Men’s story reintroduce us to these characters, so we can see how they differentiate from what Fox has given us. Given this racially charged climate we’re living in today it would make for a great MCU X-Men trilogy. Feige and co should focus on telling stories that deal with racism prejudice and discrimination and politics. I want to see Mutants being lynched, FOH,mutant civil rights protest, Magneto trying to start a war, etc. Once all that has been established then we can move on to the X-Men merging into the Avengers world and dealing with those types of threats.
