Sandaime couldn't really do anything against the Shodaime and Nidaime during the fight; he did land two exploding charms on them as a trick, but they weren't really being aggressive about killing Sandaime because Orochimaru was more concerned with mocking him. He won that fight because he realized his limits due to his age and their regeneration, so he decided to do a Kage Bunshin Dead Demon Seal.
If one of the Kages would man up and sacrifice themselves to use the Dead Demon seal on him, and could surprise Madara, the fight could be over relatively fast. It's the ultimate balancer move. The problem is I don't think the technique was passed on.
