If anything, if they made an agreement, this is gonna be good.
Working together is wonderful, if Disney/Marvel never wants the rights to the X-Men back. Because of horribly lopsided deals struck back in the 90s, Marvel takes in a miniscule amount of the profits from X-Men films - I've heard it rumored at < 5%, which given studio accounting means that they have basically given the rights away for nothing.
Because of this, it is in the best interests of Disney for the X-Men movies to fail, which is why you won't see stores filled with film merchandise for X-Men (or the FF) like you see with Spider-man or MCU films. Despite negotiating horrid deals, Marvel held onto control of the merchandise rights for all of their properties.
This move is an interesting one by FOX, but it could backfire. If this is a late addition to the script, Singer may be just setting up a character for Whedon to knock it out of the park.
