Why couldn't they just reboot it
As long as they are brothers, I'm okay with switching who is the elder of the two.
Especially if Ultimate X-Men did it that way. After all, Ultimate continuity was a big influence on Avengers too, so it has been used on screen before.
As for rebooting, the general audience wouldn't understand that. Best to use DoFP to clean the slate and make all the previous films alternate versions, so they can start fresh.
