It seems we are closer than I thought. I'm not Wiccan myself (mainly because I've no feeling for magic, so that whole aspect of their practice goes right past me,) and though I acknowledge the God, it was the Goddess - originally in the aspect of Inanna - that brought me to the Pagan paths and remains the focus of my faith.
But I'm not clear what use of names bothers you in the Gor canon. I gave up reading the books around #10 (I forget exactly); but at that point, the only religion mentioned (other than the Priest-Kings) was the Vikings' worship of Thor, which was treated with reasonable respect. Is a goddess-cult introduced later? Denuseri, you would know?
