Everything would have changed. After learning about the Mangekyo blindness, sasuke would probably take itachi's eyes. Thus activating the kotoamatsukami (crow with Shisui's eye) on sasuke. This would mean, itachi would not break the edo tensei. Maybe Nagato and Itachi could have killed Naruto and Bee. And that would have been the end card for the show.

PS: The amaterasu might have killed Kakashi(Since it was set to activate against Obito's Sharingan).
