Ok, so let's assume there's an earlier POD and a 1763 revolt makes sense:
It will probably fail, but isn't guaranteed to. We're way out in Butterfly Land here, so it's hard to predict, but the colonies will have undergone 12 less years of population increase, mercantile development, etc. Not a whole lot, but it could still be crucial. France will still be smarting from its loss in the Seven Years War and probably far less willing to go to war against the British. On the other hand, should the revolt really pick up steam, the Canadiens would probably be more likely to join in than in OTL, which could make a difference, as well as possibly drag France back into it.
