I tried searching for this, but I couldn't find anything except the scenario being suggested as a way of establishing a constitutional monarchy in France. Anyway, this is exactly what it says on the tin. Louis, grandson of King Louis XIV and son of the dauphin dies sometime before his grandfather. Since, I believe the King of Spain is blocked from the succession by treaty, the succession would fall upon the son of Louis XIV's brother, Phillipe II Duke of Orleans, who in OTL served as regent for Louis XV. Since his son was born before Louis XV, I think he would come to the throne sometime either in the 1720's or early 1730's, though I'm not sure how long lived King Phillipe VII will be thanks to actually being on the crown.
So, basically, the OTL House of Orleans comes to the throne in 1715. How do King Phillipe VII and his son who in this timeline would be known as King Louis XV, compare with Louis XIV's historical successor? What happens to France? How is European politics affected by the succession of the Orleans branch of the French Royal family?
