Well, since all the Christians left the Episcopal church and became either Anglicans or Catholics, those that remain might as well go whole hog into whatever doctrines they like.
I suppose, very relatively speaking, that the at least theoretically “mainstream” leftist wackos now in the Episcopal church would want ecumenism with Wiccans. Their “progressives” probably want ecumenism with Satanists and human sacrifice pagans.
Not sure I want to see a naked crone...hehe
