Edo observation AND Sasuke bet:

Edo one up first as promised:

So, it stands to reason that if one had no practical DNA to reform said ritual, that one may decide to turn to a living family members blood, as that would then contain said DNA...

Next up--Sasuke. Taking bets that he either gets: Perfect Sasano before Rinigan...

Unless it was an idential twin's Dna i don't think that would work. Even family members as closely related as fraternal twins don't have identical DNA.

Makes sense Oro dude, but pleading the fifth on the Sasuke bit eh...

Sasuke will most likely awaken the perfect Susano'o before he faces Naruto. There's reason why Kishi said that it's comparable to bijuus.
