There's nothing to elaborate upon. Madara's body wasn't used to revive Kaguya in the way you believe it was. What happened was no different than Blue B/Fukai's body having been used to revive Gyuki or what Kurama tried to attempt with Naruto and almost succeeded against Pain. Madara didn't contribute anything to the Kaguya make-up, he was simply taken over from loosing control as a jinchuuriki.
