 * 1) Indra didn't have a Rinnegan. He had a Sharingan.
 * 2) Rinnegan is born from the Sage's chakra, which is Asura and Indra's chakra combined. Not Uchiha and Senju DNA. The only reason it worked for Madara is because he was Indra's transmigrant and Hashirama was Asura's.
 * 3) Sasuke got half of Hagoromo's power (his chakra) therefore he awakened the Rinnegan.

Then it's also possible for Naruto to awaken the Rinnegan. Maybe he got the other eye.
