1. You obviously changed it or you would have put "similar" in the title or why put IT in the title at all?
2. I did read that, and it's a bullshit cop out. You just made up a jutsu. Your "big reason" is also poor.
3. What sasuke did was more inline with what Madara and Obito did to Kurama, not IT. Giving power ups is Kishi's job not yours. He is the author of the manga, you are the author of fanfiction. Here's a manga fact: people in IT don't eat or drink. Without shinju Naruto would be dead inside two weeks. Sasuke can't control shinju without being a juubi jin.
How does Naruto being put in a genjustu that he can't break out of for years, yet somehow doesn't die without food or water, yet the justu can be broken easy by someone else just because, fit into Kishi's plot? Sorry I don't see it. Maybe you can write the whole fanfic and post that later.
Dude, you asked me what I though of your theory. It's poorly thought out and based on fanfiction (you just giving sasuke powers just cuz) . I'm sorry if this opinion left you butt hurt, but "reading you theory properly" doesn't mean agreeing with it's dumb premise.
