Often you would hear fans speculating who should enter the frame and team up or work alongside the Avengers, lets talk about my personal favorite, I would recommend the X-Men enter the MCU and add to the already long list of heroes, Now you may be saying that there is no way to merge the timelines, so I would say let's not forget at the end of Deadpool 2 Wade was left with a time-traveling device which he modified on his own and who is to say if he did a good job after all it is wade, he could find himself skipping timelines and finding the MCU thus giving the X-men a way to join or the easier less messy way would be to re-write the X-Men into the MCU.
If the MCU goes the way of rewriting the X-Men into the MCU, the big question everyone would love to know, who plays Wolverine, Hugh Jackman has retired the role of the X-Men, lets bear in mind Logan took place in the year 2029, which still gives us all the years in between to hope he comes back and plays the hero. Hugh Jackman joins a long list of heroes who can't be replaced
