Yup, v12. (I've been playtesting it a bit when I have a chance.)
I'm not on the right computer to post the leader pedias and diplo right now, but I'll post them when I get back. (Not sure how well they work with the existing background, but I figured writing something is better than nothing at all.)
As for coding the diplo, in case you like the way I go with it, I think I can do the heavy lifting on that; I could create and e-mail you an otherwise-unchanged-from-v12 leaderheads xml file with the right references built in, and send a text file with the xml to copy-and-paste into the gametext file, if you like.
