[Orphalesion]

Yes the name connection between Kôr in She and Kôr in the Book of Lost Tales is interesting I came upon it a few years ago and it even prompted me to read it. Ayesha does seem a lot like an "evil" Galadriel and perhaps offers a glimpse of how Galadriel would have acted if she had fallen to the temptation and taken the Ring from Frodo.
It would not be the only time Tolkien was inspired by (relatively) contemporary fiction, another example Psamathos Psamathides from Roverandom who bears resemblance to a character from an earlier Children's Book (more so in the early drafts)

I find it also interesting how important Kôr was to the Elves in this early conception, much more, it seems to me than Tirion later would be. I mean in this early stage it's the Ilkorindi "The Elves that never have dwelt in Kor" instead of the Úmanyar "The Elves that have never been to Aman" and their city in exile on Tol Erresea is Kortirion (whcih could be interpreted as Kor-Tower) instead of Avallone "Near Aman". Kôr was almost an Elf Jerusalem.

In the later mythology the Elves seemed to yearn for the lands of Aman/Eldamar/Valinor and not so much for Tirion itself, with the possible exception of Turgon.
For instance, if Tirion was as important to the psyche of the Exiles as Kôr had been, Galadriel's lament would have said "Maybe thou shalt find Tirion" instead of "Maybe thou shalt find Valimar" and it would be "The Undying City" instead of "The undying Lands"
