France could easily get the Netherlands west of the Rhine if the Valois-Burgundy somehow manage to become kings of France, which is pretty unlikely given their position on the line of succession (and the fact that they went extinct in the male line in 1477).
Actually, the chances of the Bourbons getting the French crown were quite smaller than those of the Valois-Burgundy before the latter became extinct. The Valois-Burgundy were descendants of Philip II the Bold, Duke of Burgundy and fourth son of John II of France. The Bourbons, for their part, are descendants of Robert of Clermont, the youngest son of Saint Louis IX of France who is a great great grandfather of John II. A Valois-Burgundian candidate to the French throne would thus have come before a Bourbon if the line had survived.
Mirza Khan even made a timeline with a Burgundian getting the French throne. It's called "Vive la Bourgogne! Vive la France!". The Valois-Burgundy do not die out in 1477, OTL Francis I dies before Louis XII and thus a Burgundian duke gets the French crown.
It's true that the Valois-Burgundians were the youngest of the Valois branches. However, the Valois-Berry line had went extinct in 1402 and the Valois-Anjou were extinct in the male line in 1480/1481. Thus, the Burgundians would have been the next one after the three lines of the main branches, which includes :
-The main line (Charles V, Charles VI, Charles VII, Louis XI, Charles VIII) who died out in 1498.
-The Orléans Line (Charles V, Louis of Orléans, Charles of Orléans, Louis XII) who died out in 1515.
-The Angoulême Line (Charles V, Louis of Orléans, John of Angoulême, Charles of Angoulême, Francis I, Henry II, Francis II, Charles IX and Henry III) who died out in 1589.
It's thus not that hard to have the Valois-Burgundy survive long enough to get the French crown. What might be harder would be to stop Charles the Bold from wishing to become an independant King, which lead him to confront Louis XI.
