I would really suggest just running with the Insinuator antipaladin archetype (http://archivesofnethys.com/ArchetypeDisplay.aspx?FixedName=Antipaladin%20Insinuator). it trades spells for combat feats, and replaces the "KILL ALL THE PUPPIES!" stuff with self-healing, the ability to smite anyone you don't like, and some halfassed conditional group healing options.
