With your understanding of MCU time travel,Changing the past doesn't change your present. Do you think stories like DoFP/Bishop story or Cable coming back to stop Apocalypse can work in the MCU? X-men has supring amount of Time travel in it for example Age of Apocalypse starts because Legion goes back in time and kills his dad. One of the better modern stories Messiah Complex has some of time travel shenanigans. etc. Can you make Time Travel work for MCU X-men?
