I believe Minato can win this, but not in raw battle since he lacks the fire power to destroy Madara's Susanoo. He can mark his Susanoo however which has shown solidity, so from that point Madara would be forced to maintain it since if he deactivates it, the time it takes to deactivate leaves him open from an attack(FTG blitz). Minato on the other hand could just sleep and wait for his opportunity since his opponent can't hit him either. If he doesn't want, he can also use Pa and Ma for the long range frog genjutsu(strongest according to databook) however and Madara has no chance to stop it in time when he has a teleporter on Minato's caliber on the other side. Technically, Minato can win fights easy with this move, although i'm not sure Kishi would let it happen in a manga
That's featwise however since i believe portrayal wise, Madara would win
