In my uneducated opinion, it would be difficult for the Warriors to back out of this deal. First, as we've heard, this "three months" quote was just a guess, it may just be a few weeks. Second, the trade saves the Warriors a TON of money and gives them a useful asset who knows the system and who thrives in it. Third, now that they have waived the white flag on Wiseman, it's doubtful they could ever get a better return for him. Fourth, there's no way you can bring Wiseman back in terms of chemistry. He knows he's unwanted, the players know he's not part of the plan, and they'll get nothing from him this season, whereas with Payton, they'll at least get something.
