How I'd like it to end: The Hokage show up to the field and restore Sakura and Kakashi's strength. They explain that they need to seal Kaguya, but they need her weakened first, so Naruto and Sasuke dash in and begin to fight again. In the midst of the fight, Kaguya's strength begins to fade from losing her power after killing Obito, constantly switching dimensions, and currently fighting Naruto and Sasuke for more than 3 times. Soon, Sakura, Kakashi, Minato, and Hiruzen join the battle to make it more intense for her while Tobirama and Hashirama prepare the sealing. BZ senses the sealing and slips away after Kaguya is knocked on the ground, and the two brothers finally seal Kaguya which puts an end the God Tree and frees everyone. However, some of the ninja were already turned into Zetsu's and escaped (none of Konoha mains, just random fodders). Finally, they all return to their respective villages and maintain peace.
Lead into Part III: (BZ escaped and is planning something big in order to destroy all of the ninja alliance without another war to draw attention)
