I thought about this. I doubt he would because not only would that go against Sasuke's wishes which he abide by for now but Madara also stands in the way of his goals.
But for the sake of the thread, that would be sick! Orochimaru pulling some twisted shit like that would be in his character. If that was to happen, I'd imagine Orochimaru gaining Madara's trust and then backstabbing him by taking his body. It would be a great twist IMO, a little disappointing cause I like the Hokage's presence but great for the plot. I don't think it'll happen but I would like it. But I think I'll be satisfied if it doesn't happen as well
