Well, if she's still young like her otl brother, not an ideal wife anyway.
Honestly, there's a good chance she'd share the fate of Juana la Beltraneja - put away in a convent. Henry cannot risk her marrying and he can't marry her; while it may not have lasted one of the forces that got him to the throne was disaffected Yorkists who saw Richard as a usurper. To get them, he needed the marriage to Elizabeth.
Now, if you make the daughter very young - a younger sister rather than a counterpart to Edward of Middleham, best case scenario being her birth and not illness kills Anne Neville - then she's betrothed to little Prince Arthur.
