I wouldn't worry about trying to find specific character parallels. Each character is very much a gestalt of various themes, traits and antecedents. Elayne, for example, could be considered closer to Gwenevere than Egwene could, since she is a Queen, rules Caemlyn (which might be Camelot) and has been kidnapped multiple times, yet Egwene also could be considered a version of Gwenevere since she is a High Queen (since the Amyrlin Seat could be considered to outrank Queens), was trained in Tar Valon (which could be Avalon, and according to many of the myths that existed before Mallory, Gwenevere and Lancelot were allies that were raised and trained in Avalon together), has also been kidnapped many times, has served as a Battle Queen (which was one of the traditional roles of female leaders in the cultures that inspired the Arthurian legends) and has the most similar name.
