One problem: if the Elder son was made by the Sage's creation of all things jutsu, then how was the Younger son made...? It must have been the same jutsu for both, so in that case if the Juubi's foul and sinister chakra influenced the Elder son and his descendants to follow a path of hatred, then why did'nt it influence the younger son or his descendants, who were also the sons of the Sage?
Tobi already explained this, when he said that the curse of hatred of the Uchiha was born out of the decision of the SO6P to choose the Younger as his successor, not some after effect of the 10 tails chakra.
And you should'nt even think of 'the best theory on NB' as best is a relative term. Besides, what great questions have you answered? As i proved above, the very basis for half of your theory is false and shows a poor understanding of the manga. A good theory has the hallmark of sticking to facts, and providing reasonable proof where appropriate, not twisting manga pages and statements to prove a pre-conceived notion.
You want a tip? Some of the locked/merged threads about Who is Tobi...? were true masterpieces on the art of making an epic theory thread, look them up.
Nonetheless, this must have taken some time so props for that, and the presentation was good. You should try to be more impartial though with your thoughts.
And there is definitely a correlation between Zetsu cells, Oro's curse seal chakra and Hashirama's DNA as used by both Kabuto and Tobi. Zetsu seems to be compatible with the 1st's cells, much like how Kabuto is compatible with Oro's curse seal as seen on Anko's body. Still, there is not enough info on this to reach a conclusion so i won't dwell into that any further.
Well, according to the interview Naruto and Sasuke are meant to be equals.
