I think it would be AWESOME!!!!
I thought for a very long time, that without an actual corpse, and without the actual completion of the summoning of the 3rd coffin, that Yondaime is still alive as well.. However.. erickaujero and blackmamba posted info regarding the jutsus used by both Sandaime and Yondaime in order to summon the death god, which requires a sacrifice..
hmmm.. now that I think about it.. maybe Naruto's mother died instead of Yondaime during the ritual to seal the Kyuubi...
Just trying to back up your current theory (as well as my old one) cause I'd really love to see your prediction come true..
