http://www.gamesas.com/index.php?/topic/1067967-khajiiti-tower/page__hl__tower+khajiit__st__20 seems to speak to that though the discussion seems to drop off a bit without a clear consensus.
One interesting thing I learned from that, aside from the Khajit 'tower', is that Martin reestablished the white-gold tower with his sacrifice. Is this generally agreed upon? I personally thought Akatosh merely banished Dagon then left, leaving the tower vacated?
No, I'm all fairly certain that White-Gold still stands, given that it still stands.
I disagree with the gist of the thread that all towers are connected with the eight divines, seeing as how the eight divines are an invention of the Cyrodiil and except for Akatosh have nearly no mythical importance. They are all linked to the Doom Drum or the Dragon.
Adamantine is the condemnation of Lorkhan by Akatosh.
Red Mountain is the wound of the world (Lorkhan) by the falling of his heart. You might say it's the hole in his chest made manifest.
Crystal-Like-Law is obviously the seat of the High King of Alinor.
Walk-Brass is the harnessing of Lorkhan. Even when they lost the Heart, the Mantella worked because it was the heart of Lorkhan also.
Snow-Throat is the mind of Lorkhan. Lorkhan commanded the et'ada to form Mundus just as thu'um commands them inside Mundus.
White-Gold is the perfect gem of compromise.
The Khajiit are the binding of Lorkahn's body to Mundus.
If anyone has any information on Orichalc or Green-Sap I would be grateful, though balance would dictate that they are both of the Dragon.
