In the original story, people from Oz thought that Dorothy was a witch because she was able to kill WW of the East.

To get back to Eva is the GWoN theory, there are many similarities between GWoN and Eva as there are many similarities between Mombi (WW of the North who was deposed by the Good Witch) and Cora. I'll just quote some things about both characters from Wikipedia:

1. Good Witch of the North ''L. Frank Baum presented her as an extremely kind and gentle character who stood against the oppression and subjugation of people. However, the character's kindness and magnanimity of spirit was not confined to her own domain, and she was loved not only by her own subjects but also by other people in Oz.'' All of this definitely sounds like Eva to me.

2. Mombi, Wicked Witch of the North Transformations seemed to be Mombi's forte. Cora was master of transformations herself. ''Even after her defeat, Mombi was still a survivor. She made herself appear to be a lowly wizardess and settled down on a quiet farmland'' Cora from Stable Boy comes to mind.
