The French never accept New France and loose Carribean. That not in cards. The $$$ was in Carribean.Here's an idea:
1) The Albany Plan of Union goes through, resulting in the unification of Maryland, Pennsylvania (including Delaware), New Jersey, New York, Connecticut, Rhode Island, Massachusetts, and New Hampshire.
2) In the peace at the end of the 7-Year's War, Britain demands that Guadeloupe remain British. France thus retains Canada, although the border is set at the Great lakes and Ohio River and Britain gets OTL New Brunswick, Prince Edward Island, Cape Breton Island, and Newfoundland island. The Southern colonies are happy, as they get their boundary claims extended to the Mississippi. The northern colonies may have gotten a bit of a buffer, but on the whole they feel cheated.
Backed by the French, the northern colonies later declare independence.
