And regardless, if Orochimaru uses Impure World Resurrection to summon the 1st and 2nd Hokages as immortal zombies... Beowulf and the Basilisk can't kill them and have no way to seal them, so they can't win.
He can't use that technique since it requires a living sacrifice of another human. Well he could use it and sacrifice the 4th hokage but otherwise he couldn't by the rules of the fight.
