The Bavarian swap thing was a decade later under a different ruler. It shouldn't be in play at the end of the seven years war. It might have an effect if OTL's bavarian succession crisis hits because while virtually no one wanted Austria to have half of Bavaria (the deal), it was Prussia who actually stood up to them. Here, any Prussia existing would not have the oomph to stand up to Austria. If Russia doesn't make Austria back off, France would have to decide whether to continue meddling in America, concentrate on the continent, or try doing both. (presuming history proceeds as OTL.)
What's Britain going to do about stopping France from gaining Austrian Netherlands? France has lost pretty much everything, but they must have something left non continental for Britain to take. Britain rules the seas and can take anything they want from France and their buddy Spain. Every day France stays in the war, Britain gets stronger. As it OTL ended, a lot of English were upset such an easy peace was settled. They could have easily demanded more. Britain holds all the aces, while France has one pair of two's - Minorca. Britain doesn't have to land a boot on the continent to make France cry uncle.
