They might try to keep up the Reunion Wars (had those started yet?) until they reached and fortified the Rhine. Also might once more try for influence in Italy. They gave up their claims to Milan and Parma centuries before (From a difference branch of the Capets, so they might not even have a claim), but I imagine they would still want to get pro-Bourbon republics and relatives in charge their. Maybe move into Piedmont if they want to make themselves look even bigger on the map. It all really depens on whether dynastic, domestic, or territorial expansionist policies are consistent over the centuries to follow. And I see them having an eternal alliance against them by the Spaniards, English, Dutch, and Austrians. Maybe not too big a change there, though.
