That would be pretty crazy (at least the Sasuke part).
Actually it would be even crazier if Sakura went to do it, but at the last minute Kakashi threw her out of the way....it would be like how Sakura was trying to stop them on the rooftop, but because everyone is stronger: 1. She got imbetween them. 2. Kakashi managed to get imbetween them pre-last second, but had to move Sakura. 3. Naruto and Sasuke's power is too much for Kakashi to stop.
Then we'd see his face

...or what was left of it... :'(
Only way I would have seen her dying in this war would have been because Obito saw Rin in her, or she died to save Hinata (because she knew she loved Naruto)....BUT now Obito sees Naruto and Hinata hand in hand as well as the fact Naruto is ready to save Hinata (who also doesn't look like she needs nearly as much saving as she used to).
So this fight would be the only time she would most likely die...
