This is a very interesting analysis of the theories. My previous comment contains some of my responses to your pros and contras, though it is more applicable as a reply to your response to my first comment.

Another question which comes to mind is: If Vivienne was a High Priestess, why would she work as a lady-in-waiting, which is essentially a servant, for Ygraine? This would lower her status in the world. However, perhaps she was destined to help and protect Ygraine so that the woman could fulfill her destiny of giving birth to Arthur (like the powerful sorcerer Merlin protects and serves Arthur). Also, how was she allowed to marry Gorlois, who was Nobility (we know this because he was a knight and the First Code of Camelot says that only Nobles can become knights). Did her magic (or her elevated status as a High Priestess -if she in fact was one- ) have something to do with the match? Clearly, the marriage was not a love match, like Guinevere's and Arthur's was, since she had the affair with Uther (unless, of course, magic was involved in this affair, as was the case in many of the versions of the myth and the Guinevere/Shade!Lancelot romance of Series 4, Episode 9 of the show). So, why did this Knight end up marrying a servant girl?
