A French King with a claim to Hungarian throne

Since I know that the claims of the French to the Duchy of Milan came from Valentina Visconti, what if Mary of Hungary escaped and managed to marry the duke of Orleans and their descendants become Kings of France, how would that affect France and would France try to claim Hungary in the same way as they claimed Milan in otl and how would it affect the Hundred Years War and would a war of succession for Hungary in the same way as Milan in OTL?
