Except 1) Naruto wouldn't have lived. The only reason he survived is because Sakura became his pace maker.

2) 10 Tails easily dwarfs all other other beasts. Even Kurama looks like a punk next to him. Obito only survived because of the Gedo and Madara died within minutes, and he since obsorbing the 10 Tails, would have the same physical properties as Hagoromo. Hagoromo wouldn't have survived without the Gedo.

He either: 1) brought it down and lived with both its parts seperate but inside of him

2) brought it down just before he created/released the Tailed Beasts so that he could tell them of the prophesy, name them, etc etc.
