I just re-read this, and this is still awesome. Some more questions though!
I love what you did with French North-America. The polarization between Canada and Louisiana is awesome, and I love what you did with the Upper Country, this weird network of local and wider alliances that emerges into a state, a mini-ASB of some sort. That's IMO a very good take on what an evolving network of Indians and French Canadians might look like.
But on the other side of the spectrum, what would an alliance between natives and Louisianians look like? Wha, t's happening in the Indian states between Upper and Lower Louisiana?
Also, I'm interested in St-Pierre and Miquelon. IOTL it's already something of an oddity, and actually wasn't even French before the Treaty of Paris, where France was given the islands and lost the rest of New France. It didn't happened ITTL, so how did St-Pierre became French, especially in light of a english Newfouldland? And how did it became an ASB State (it's population IOTL is of 6000 inhabitants)? Was it a part of a treaty in which France renounced to Newfoundland but was given the islands to keep access to the Newfoudlands Banks, as IOTL?
Also, with such a differend history of North American colonization, what happened in the Lesser Antilles? IOTL the british islands gained independance quite late (in the 1950s), the dutch islands are autonomous and the french islands are fully integrated into France, but with the example given by the ASB, I think it would be fair to say the british islands would be tempted to form a Lesser Antilles Confederation, perhaps to be joined by the dutch islands.
But before that, IOTL the Lesser Antilles were hotly contested between France and Britain. ITTL with a weaker England I could see some of the islands remaining french (Dominica at least, perhaps also St-Lucie and St-Vincent) but at the same time, with France still havig Louisiana and Canada, perhaps they would be less interesting in the Antilles (though I'm doubtful of that, France did prefer retaking Martinique than keeping Canada at the Treaty of Paris after all).
Also, Dominica itself is a rather fun place - a very mountainous island, which allowed the Caribs to resist longer to European colonization than any other island: in 1660, France and England abandonned the islands to them, making it officially a "neutral island of the Caribs". Of course this didn't last long, what with the island being right between Martinique and Guadeloupe, and Dominica became officially a French colony, which was lost at the Treaty of Paris, though they would try to retake it until 1814. Today it's the only island with a Carib reserve. Perhaps ITTL the Caribs managed to exploit French and English rivalries (and ASB precedent) to make Dominica a Franco-Carib State?
