"Correct" interesting way to frame it, considering the role was written to be played by an adult woman, including the vocal range for the songs. But I guess there's potentially some heightened emotional/thematic immediacy that come come from having an actual adolescent boy play the role - it's been done before, but not in a major production of this specifical musical adaptation, to my knowledge.
(And while I don't approve of non-union tours, it's hard to deny that this IS a major production, considering the fact that it's directed by Lonny Price, with a brand new book revision by Larissa FastHorse)
