Yeah, personally I've held to the belief that sorta reconciles the two leading stances - Nozarashi just took the visual form of Yachiru, since Kenpachi was familiar with her. That, of course, doesn't explain what on earth HAPPENED to her during the last arc after the Gremmy fight, but it sure makes a lot more sense than a Zanpakutō spirit having its own different, uniquely named Shikai.
