Philip IV of France died in his 40s. It would not be inconceivable if he lived an extra 20 years. Suppose that is the case, and he outlived all of his sons, how would he respond to the looming succession crisis assuming all his sons still failed to produce living sons whose legitimacy could not be questioned? Would he have remarried and tried to father new sons? Potential brides? Would he have outright denounced Joan II of Navarre as a bastard as his other son attempted to do? Also, what would he do if he couldn't get more sons? Would Philip have appointed his Valois nephews as his heirs or is there an upped chance that he would appoint Edward III as his heir suppose that he suspected all his granddaughters including OTL Philip V's children were also bastards?
I think his most likely solution would have been to try and father more sons first and likely would have thrown Joan under the bus the Duke of Burgundy be damned.
