What If Itachi Had The Rinnegan - The Amagi

Maybe this was just me, but I had a realization not long ago. And after having it, it lived rent free in my head ever since. Sasuke’s eyes never turned into the Rinnegan. Now, you may be looking at your screen funny, but hear me out. Sasuke Uchiha’s eyes were going blind from Mangekyo Sharingan use, and so he decided to attain the Eternal Mangekyo Sharingan instead. And when he attained the EMS, he had to replace his own eyes with transplants. Specifically from Itachi. So from the point after Sasuke retreated from the bridge in the Land of Iron, his eyes were no longer his. They were Itachi’s. Which means that, during the Fourth Shinobi World War, the eye that became a Rinnegan was actually the eye from Itachi. What I do kinda find funny though is that, when Itachi was reanimated and cast Izanami on Kabuto, the eye he used was his left eye, the same eye Sasuke would turn into a Rinnegan, so there’s probably a lot of significance to this which I could and probably will give its own video to. But for now, I’d like to finish explaining how this idea correlates to the What-if at hand. What if Itachi possessed the Rinnegan?
