Hopefully not, who would want to worhsip this heretic cult of the false "ninth divine"? <Enter Thalmor Inquisitors>
(Besides, Daedra and Ancestor worship of the Dunmer is the true way to go, anyway. Heed the words of St. Veloth!)
Anyhow, it sounds like something a mod could explore with lots of opportunities to make the game more interesting and add another layer of politics/relations/character roleplay motivation. But I think for the obvious risks of real world parallels stirring up hatred/hurting religious feelings/making people go crazy the devs will make the choice of most games: Ignore the issue for the official game.
