Yeah, the evil ones are quite diturbing, especialy Shaelana. I think that is mostly due to the sensitive parts of the male anatomy involved, but still.
This mod looks like it could be pure awsome. The end of the tech-tree seems to move into magically powered steampunk witch is awsome, and the leaders are interesting (if a bit disturbing). I've following the developement for a while, and it keeps getting better!
I've got some spell ideas floating around, if you are still interested. They mostly involve necromancy, and since you havn't posted anyting about how you plan on implement it they might not be suitable for the mod. Still, if you are interested i'll post them.
