Well, I don't think Louis d'Orléans will be divorcing Jeanne de France to marry Anne of Bretagne any time soon. Although, if Charles Orland lives, he would be of the right age should Ferdinand of Aragon still piss of Henry VIII enough that Henry marries Mary Rose Tudor to the French king. Instead of getting a tired old man, Mary gets a young husband (unlikely to die in the sack

).
Also, Charles Orland will need a regency if his dad dies on schedule, so then Anne de Bretagne and Anne de France might butt heads over who gets it. Probably Anne de Bretagne (since she was the young king's mother) but Anne de France had a very forceful personality, so she might get it instead.
As to French foreign policy, the Italian wars of Louis XII would be butterflied to only occur later (due to the young king being just that - young; and regencies are never good for wars, so an early peace if Charles VIII is still bickering with the Italians).
