What has Nakomi done that gives any reason to think she has anything to do with the creator?
To me she was a blunt instrument to get Avi thinking about the future of the Aiel and prepped (unnecessarily IMO) for dealing with her final trip through the glass ter'angrel. Avi's desire to help the Aiel people after the LB was aided by discussions with other WOs and didnt strictly need Nakomi.
Besides, why is helping the Aiel to not become what Avi envisions creator-worthy? Yes it would be sad to see the Aiel degraded but the creator made and let the Seanchan run free and other cultures be eviserated (Sharans) without intervention. Why are the Aiel suddely so special?
Likewise, if indeed it was Nakomi who helped Rand body switch (I am not convinced) again, why? The DO is tucked away and Rand "living" in hiding is no longer relevant to the pattern. He did the rest of the hard work on his own, why should intervention start now?
