So, here's something I've been wondering, in otl as part of garnering support for the nine years war, Louis XIV agreed to marry his grandson Louis Duke of Burgundy off to Maria Adelaide of Savoy. However, was there ever a chance, as part of a peace process with Emperor Leopold that he could have married off his grandson to one of Leopold's daughters, perhaps say Maria Anna (b. 1683) who otl married John V of Portugal?
If not her, who else could the Duke have married?
