Okay, so according to scenario of OP, the event thats leads to Uchiha Massacre would never happen, right? That means no Kyūbi Attack, no Danzō's attempt to get Shisui's Mangekyō Sharingan, no Shisui's suicide and Itachi not having Mangekyō Sharingan(since Itachi awake it after seeing Shisui's suicide). Not sure about Sword of Totsuka and Yata Mirror, since it's not known when exactly Itachi found those two tools.

Also, technically, wouldn't also mean that Obito doesn't "die" in Third Shinobi World War, but actually get back to Konoha, and Kirigakure doesn't seal Isobu inside Rin, which leads Obito witnessing Rin intentionally getting killed by Kakashi, which awakes Obito's Mangekyō Sharingan, getting Obito suspectible to Madara's manipulation and causing the Kyūbi Attack. While not immediate events, they also leads to Uchiha Massacre.
