Could the Fantastic Four realistically even fit into the Disney MCU

Realistically could the Fantastic Four realistically even fit into the Disney MCU? I mean could the Fantastic Four mesh with The Avengers in a realistic setting since you have The Avengers all of them Iron Man, Thor, Cap, Hulk, Hawkeye, Black Widow, now Scarlet Witch, War Machine, Maria Hill, Nick Fury and Falcon could the Fantastic Four fit into the mold?

Fantastic Four no doubt would be tracked by SHIELD with SHIELD or Fury keeping tabs on all of them and their escapades

And Dr. Doom would make a great villain for all The Avengers to take on
