James Mangold is working on the new Indiana Jones movie for one subsidiary of Disney, maybe he’ll endear himself enough that he’ll get a chance to continue this story.
If Deadpool has a chance to continue in the MCU, or at least adjacent to it, then maybe there’s a chance for other characters, like X-23, to do the same.
Unfortunately, with the acquisition of Fox by Disney and the ending of that particular cinematic universe, it’s unlikely, though certainly not completely impossible, that such a movie will ever happen.
