Guy will break Perfect Susanoo with Evening Elephant and kill Sasuke with Night Guy. If Evening Elephant can't destroy PS, then Guy will use Night Guy and destroy PS and kill Sasuke. Sasuke's perfect susano'o took hits from rikkudou naruto without breaking, and naruto's lava-rasen shuriken did similar damage to madara as gai's night guy, so It wouldn't be unreasonable to say that his susano'o can tank this damage. Maybe not multiple times, but that isn't a move that can be used multiple times, and this is assuming the small chance that gai actually forces sasuke to use PS as a defense when there are plenty of spots to go on the offensive (Read every other comment in thread for arguments)
