Nah, I think that, the way he was going, Madara would have been defeated by Naruto/Sasuke's combination. His Limbo shadows were easily fended off by Naruto's Kagebunshins, and Madara's destructive power was matched by Naruto/Sasuke. Add the fact that Naruto could have gathered the massive amounts of natural energy (as seen in 696) at any time, and it's clear that Naruto/Sasuke would take the lead in this.
Madara didn't really do much with his Juubi powers; I think Kishi wanted to reserve the "Bijuu Susano'o" thing for Sasuke, and apparently Kishi forgot that Madara could use Mokuton (aside from casting the Infinite Tsukuyomi).
