Skill Base Ability Score Changing Diplomacy from Charisma to Intelligence


I’m not sure if my google-fu is just off tonight or if there’s a way to change the 3.X/Pathfinder skill Diplomacy from being a Charisma based Skill to an Intelligence based skill.

I’d prefer 3.X (including sources like Kingdoms of Kalamar) and Pathfinder to be open… as well as a few other not so specific sources like Green Ronin press, or Book of Erotic Fantasy, etc…

I’m trying not to homebrew something myself, or to at least use outher sources as a reference. I’ve already looked at the X to Y reference, but didn’t find anything for changing Diplomacy form a Charisma based skill to Intelligence…
