Also, I think there's a reason for Hashi to make his wife Mito Kurama's Jinchuriki instead of becoming it himself, so Hashi's "compatibility" is as questionable as the "compatibility" of any other powerful Uchiha. They are, both Madara and Obito became JJ because of that and Danzo wanted become KJ using it.
