Since this tour is about Tom Petty's "highway companions," I think it's fine to give the guests a little more stage time than usual. Since all of the songs Stevie sings on are written by Petty, I'd imagine his fans wouldn't mind too much seeing that they are
still Petty songs. Stevie and Tom came up together in the music scene, so I would hope that people would appreciate the history they have and not view her as an outsider.
