Yes(ish).
I would like to have my cake and eat it too, with both studios having access to the whole universe to tell the full story they wanna tell. Film rights, copyright et all just not the way it works.
Also a growing part of me thinks that is too late to introduce the X men into the mcu. No more possibility for Logan and Cap ww2 adventures, not really excited for Holland's Spiderman and Wolverine to interact, no Storm and T'Challa. Since there have never been mutants no scene like Emma Frost reproaching Mrs Marvel about the Avengers lack of care against mutant atrocities. Illuminate members off the table (plus the in my opinion botch used of planet hulk).
On the other hand I think there are some cool interactions waiting for the FF4. I think Holland's Spiderman would suit well with the FF4. Interact with the Hulk and maybe bring in She-Hulk. Introduce Namor (make it a Civil War style crossover for a big battle with Atlantis).
