Another thing for you to consider: Mombi from the 1985 film Return To Oz, as portrayed by Jean Marsh. Clearly very Zuul-coded, except flashier.
I can't say that the character of Mombi wasn't inspired in some way by Zuul possessing Dana, because they do look very similar. And add into this the fact that Mombi in the original novels was a traditional hag it seems more obvious. I mean look at them -
However I will say this might be a case of that just what was considered 'The Look' at the time. Big hair was in, the bigger the better, with the dark lined eyes and a light lipstick. I think it's a case of a little of column A and a little of column B.
