Reading your PM I can tell you:
I have done a lot of things for that, but there are some differences in the gamesystem and my work is stopped at this point (25 level classes, 10 level spells, and some other things). For me it is working to a special point of use, but it is not perfect. I think the Pathfinder dataset has a more potential to do some things better, but the best way would be a full editable ruleset for this (like the way the 4ED rules are).
