Princesses earning valor by Diplomacy is pretty iffy, as they'll just end up married to first faction that has a single Prince. Better to us Emissaries for this task. The valor either earn this way is only of benefit (IIRC) in diplomatic persuasion and in resistance to assassins. Don't think it improves heirs at all.

It might be an interesting experiment: only ask for ceasefires/alliances from factions with no single heirs until the Princess has many stars, then marry the Princess to your own first-in-line heir - see what pops out sixteen years later.
