Looking at Europe:
How are Swedish and Russian relations ITTL?
Poland looks tempting to Prussia, Austria, and Russia to tripple team and divide it up.
The Balkans look halfway stable. The minorities of Austria-Hungary and Serbia though may be the problems.
I see your foreshadowing of unrest in Europe could be:
1. Dutch citizens rise up, Flemish do the same
2. French citizens rise up overthrow empire, create next republic
3, Catalons rise up
4. The Germans in the French empire rise up to be free Duchy again, Hanover? or want to join the Prussians.
5. The Italians under French rule rise up want to be part of one of the kingdoms or create own kingdom of Piedmont.
Prussia goes after Mecklenburg as well, or Prussia and Austria duke it out for
France is chaos may have power moves elsewhere like the Russians and the Prussians going after Poland, the Austrians may come in for Silesia as well.
Minorities in the Balkans
The Bulgarians and Greeks go at it
Russians go after Swedes for more of Finland
Basically while the French have to deal with internal strife, they are distracted and the rest of Europe plays, old rivalries come back. Pax Francia in Europe is over. The British love it as they fan the flames of the French discontent. Maybe not a global war, just several local wars as rivalries and positioning come about. While the French focus inwards, the Russians strive to be the next continental power.
Would be great if the Americans get some payback to France as well for what they did to Georgia and the Carolinas. Not by threatening Quebec as by this time, the USA does not want or need Quebec, but by joining the British and supporting the unrest in France, Netherlands, Catalan, Italy, Flanders ... with weapons and supplies.
Thanks for the map it does a lot to see where current positioning and future conflicts rise up.
