Does anyone have any recommendations for Mistresses in the Bay Area who are really into either of these kinds of role play? . . . Or preferably both, as in a conversion ritual to the "Church of the Divine Feminine"?

This was a role-play that many Dommes used to list on their websites in the Bay Area specifically. I know many Dommes are highly capable of creative role-playing, but it's always much more fun when you know that the Domme is just as into the role-play scenario as you are, and it avoids the risk of "scripting". I had an amazing session with a now-retired Domme at The Gates a while back that testified to that.

Can't speak to what someone will or will not do, but I see Dominatrix Rin posting a lot of content that reminds me of this topic, and she's in San Fran https://www.xxrin.com
