Hagoromo chakra consists of 5 elements, yin, yang, and yin-yang. Indra chakra holds the sage yin chakra. Asura holds the sage yang chakra. Combined asura and indra chakra you get sage chakra to awaken a dual rinnegan. Sasuke has Indra chakra(sage yin) combined with hagoromo chakra(sage yin, yin-yang) giving him one sharingan and a in-completed rinnegan. Naruto has Asura chakra(sage yang) combined with hagoromo chakra(sage yang, yin-yang) giving him the ability merge senjutsu charka with sage chakra to form senjutsu sage chakra. The only two ways Naruto can get the rinnegan is through blood transfusion from Sasuke or absorb enough of Sasuke chakra and merge with his chakra. The only reason I see Madara didn't access 6 path senjutsu because he didn't merge the senjutsu chakra with his own chakra instead he channeled in it through the Hashirama face.
