Yamato becoming the next shogun until Momo comes of age has a lot of potential
The idea of a proxy shogun has already been introduced
We could have a contrast of this moment:
Instead of a lying, insidious gremlin becoming shogun seeking only to do harm to the country, you'd have Yamato set on trying her best to prepare it for the Momo, the son of the man whom she admires. Yamato is:
-Strong
-Outspoken and defiant
-Female
-Has the blood of a daimyo killer
-28, Same age Momo would've been if he'd been allowed to mature instead of travelling through time
-Admires Oden
The first two points being leadership qualities and the rest are points that would carry meaning for the Wano citizens.
The straw hats leave islands better than when they came. Not just by defeating the big bad, but if there's an issue amongst the citizens, social relations improve amongst the people too, even if this is not a direct result of the straw hats' actions. This has been shown time and time again from the mending of relationships and coexistence of the Shandians and the Skypieans, the closing of the fishman district and the inclusion of its residents onto the mainland and the same happening with the Tontattas being introduced to the citizens of Dressrosa and properly living among them instead of simply being a myth. Or how Inu and Neko made up, uniting Zou despite that having nothing to do with the straw hats.
This happens literally all the time. Orochi and Kanjuro, as shite as they are how been portrayed to be monsters of Wano's own creation.
A child becomes evil after watching their parents murdered in front of them due to persecution against their family and people think this sort of BS is gonna stick in the country by the time they crew leaves???
Obviously not...
Likewise, you think we'll end this arc on a satisfying note having risked our lives to save these types of people:
No...
The fact that Yamato "coincidentally" encapsulates many qualities that the people of Wano wrongfully have issues with means it's a possibility that she'll be used as a figure for changing them. Yes Orochi and Kaido are responsible for Wano being the shit hole it is, but some of the blame goes towards the citizens too for hunting children simply for being related to criminals, and as a result turning those children into vengeful villains.
The best way to make that change across all of Wano would be by having someone like Yamato, who is related to a daimyo killer... who is a woman... who is outspoken... to become the shogun of the whole country, even if only temporarily. Countering the damage Orochi did when he was proxy shogun by instead fixing Wano's dated society, helping the country rebuild and setting the stage for Momonosuke's reign.
Yamato doesn't even know that Momo, Hiyori and all the scabbards are still alive. The reason she decided to "become" Oden was on the illusion that they were all dead and that there was no one left to carry on Oden's will. When she finds out that the closest inheritors of Oden's will are still alive she could become her own person. Desiring to become shogun would be a great indication of that change as that is something Oden never wanted to be.
