Diplomancy really gets pointless past maybe level 8-ish, since by that point your Diplomacy score is just High Enough. I'd probably dip more classes for skill boosts (Totemist for Lamia's Belt and more essentia, Bard for the half-elf substitution levels, Exemplar for the competence boost, and similar until eventually just take things for the 1 rank per level). Feats would just be things that give +3 or +2, such as Vow of Nonviolence -> Vow of Peace, Persuasive, Negotiator, and probably others if you take the time to dig them out. Past a certain point, it no longer matters what you take.
