Not really, it didn't seem necessary. I imagine they would be roughly the same though, except maybe for the former-Mexican states. I can tell you that the capital of New Texas is Mexico City and the capital of Cuba is Guantanamo though.
I can only think of some for Western Canada and Alaska for now, but I'm sure you can still think of some for the other states.
Alberta-Edmonton (Same as OTL) British Columbia-Victoria (Might need to be given a different name) (Same as OTL) Manitoba-Winnipeg (Same as OTL) New Russia-Unalaska (Also known as Dutch Harbour) Nunavut-Frobisher Bay (Iqaluit in OTL) Northwest-Yellowknife Rupert's Land(Might need to be renamed to Athabasca)-Fort McMurray Saskatchewan-Regina (Same as OTL) Yukon-Dawson
Tell me what you think of this so far, and where it needs improvement. Think of this as something like an eye for an eye for an eye.
