While I certainly would not be opposed to that, I'm more of the thought that Disney acquiring Fox means any future appearances of Laura in the films is incredibly unlikely. Disney would likely reboot the whole franchise and recast everyone, and differentiate it from the Fox films as much as possible.
Plus, you can't explain Laura's existence without Logan, so the likelihood of them omitting Logan (who is still one of the X-franchise's most popular characters) and just inserting Laura in the films wouldn't ever happen.
