Have him time-travel back to day 1 and then somehow he dies and we reset.
Aliens fuck off for good, no more Kara either.
He's no longer a zoomer brat, but just a little arrogant and a spaz.
Leaf isn't nearly as industrious anymore, just a bit more advanced than part 2.
Naruto is struggling with his role as a hokage, and the leaf boomers are getting nervous.
The ripple effects cause Bort not to resent Naruto, but the structure and village in general, which causes conflict between them.
He still wants to become a ninja because he idolizes Naruto, but he's also forcing it a bit because the passion isn't all there.
After becoming a genin, the series would emphasize the leaf a little less at first by exploring and fleshing out the world.
