That still doesn't really make sense, because you need the chakra of Hamura (akin to Sasuke needing Hagoromo's chakra to awaken the rinnegan) or you need the chakra of his descendents (the moon dwellers + Hyuga), akin to Madara requiring the chakra of Hagoromo (Asura's reincarnation) to mix with his own (Indra's reincarnation) to awaken the Rinnegan (Asura+Indra=Hagoromo).
