In this scenario, Napoleon decided to dismember either Austria or Prussia.
Some questions for Austria:
— Will Napoleon try to remove Bohemia and Moravia from the Habsburgs? Will it be independent, or will it be annexed by one of his allies (Bavaria/Saxony)?
— Will the Habsburgs retain Hungary? Napoleon tried to make it independent but failed. Are there any possible options for him regarding this?
— Will Austria proper survive intact? If so, will it be a puppet state?
For Prussia:
— Who gets Silesia? Saxony? Poland?
— What happens to the other Prussian lands? Will Napoleon forcibly break the union of Brandenburg and the old Prussia? Will the former be allowed to exist, or be annexed by (possibly) Saxony?
— As for West and East Prussia, will it be an independent state or be annexed by Poland?
— Will Napoleon offer chunks of former Prussian territories to Russia, in exchange for a long-term relationship (and an alliance)?
Any other scenarios?
