That's why having a separate studio manage the X-Men titles doesn't feel forced at all, and is actually canonical when you think about it.
But yeah, trying to carve out a niche in the X-Universe for the FF *does* feel forced. It's understandable why Fox wants to do it, but it's really apples and oranges. Tonally and thematically, the FF share a lot more with the MCU than with the FCU. Fox, and fandom, would be better served by expanding the X-Men universe by spinning off films like Cable and/or Deadpool, Excalibur, New Mutants, Generation X, X-Factor, X-Statix, The Brotherhood, Storm, Psylocke, Dazzler, Cloak and Dagger....pretty much an infinite bunch of stories to draw from.
You could link the X-Men and FF together but they don't have a huge amount of common ground with each other. If I was going to link them then I guess the cosmic X-Men stuff and the cosmic FF stuff would be the way to do it (Shi'ar, Kree, The Brood , The Phalanx). I don't think alot of people want to see wanting the space based X-men stuff though. The X-Men films have generally been slightly more grounded so far.
The X-Universe is like a universe in its self. There are so many characters, teams, storylines, multiple realites, ect in the X-Universe that you don't really need to link them together as there is so much depth.
