Eh. I was thinking more along the lines that SI come along in Naruto-verse, shoves Obito out of the path of the rock that would have crushed him, winds up getting crushed himself, but before he dies he tell them both that if they hurry they can save Rin, and how.
And just like that, the story of Naruto is absurdly butterflied. Obito never becomes Tobi, Kakashi becomes a (somewhat more) decent human being, and we got Rin around. Because Obito doesn't go all evil, he doesn't puppet Madara into messing with the Kiyubi when Naruto is born (although I wouldn't be surprised if someone else tried something... and got utterly curbstomped because Minato doesn't mess around). Oh, and the Uchiha Massacre probably doesn't happen because Obito isn't stirring the pot via Madara.
