He would get a lot of hate from all the fandom for not concluding things up
Though it would be kinda better than we got
Here is what I would've done if I was Kishi, the series ended off with those 2 final pages and everyone is pissed like "GOD DAMN KISHI YOU kitten WE DON'T EVEN GET TO SEE THEIR FIGHT SCREW YOU!!!"
But you expect that kitten coming so with that final page you put a little announcement, "Naruto is over, but there are still some things that need to be cleared up in which a sequel series will release in the spring of next year. Naruto's story may've ended, but the series is far from over."
The sequel series would focus around Naruto's child who is viewed as the Hero's child, and lives with Konohamaru because Sakura who is the mother told him to watch over the child as she goes to search for Naruto who went missing. 12 years pass by Sakura still hasn't returned from her mission to find Naruto, and the child makes it his life-long goal to get the family back together. As for Naruto vs Sasuke people like Kakashi, Iruka, will make references into what went down, but ultimately it won't be until the child comes across Naruto and Sakura who finally how the fight took place, but also find out why they haven't been away. The reason you find out why Naruto's been away from the village is because he essentially becomes the new Jiraiya where everyone in the village thinks Sasuke died at the hands of Naruto, but the reason why Naruto is away is simply because he wants to know about The Uzumaki Clan and why Kaguya was doing what she thought was right during the war.
That is basically how I would've imagined it if the series ended at Chapter 692.
