IF France wins the F&IW, the Ohio Valley and everything west of the Appalachians would be French Territory. That region is what the war was fought for, so if France wins, France gets it. They also disagreed over Acadia and northern Maine and northern/western NY. Britain took control of Acadia early in the conflict. Depending on POD/how we get to French Victory (and how total the victory is), Britain may have to give all this to France.
In this ATL, speed of victory will determine if Spain joins the fray. Ferdinand VI remained neutral, and died in 1759. Carlos III was very much anti Britain, but needed a few years to get the country in shape to jump in. If the war plays out with Spain entering the war on the winning side, they get to keep Florida. They may make gains in Georgia. They lose out on Louisiana, unless that was handed over to induce Spain to join (OTL, such an offer was made, but Ferdinand declined).
For a pathway there, let's kill off Pitt and with him the whole change of war prosecution that led to British victory. Add in a dose of French military competency to seal the deal. Or perhaps Ferdinand dies a decade earlier, bringing Carlos to the throne in time to make a difference in the war.
In this ATL, much of the impetus for US independence gets butterflied, but not all of it. Unlike many others, I don't think fear of New France is much of a factor. OTL, British Canada is far more of a threat, and the Patriots still gave independence the thumbs up. Also, OTL, the colonies wanted a free hand in conquering the French, but were ignored/held back by Britain, who went to victory on the backs of non-colonial troops. In this ATL, the colonies are miffed at Britain for bungling the war - a war that the colonials thought could have been won by colonials.
The BIG thing, though, is that neither France or Spain will be all that interested to setting precedence for colonial independence. Having won the prior war, they'll have no burning desire to enter another war just to knock Britain down a peg. Without French and Spanish assistance, the Patriots have to find a different (and much more difficult) path to independence.
