Is there a way for Naruto to get the Rinnegan? Madara was able to get the Rinnegan by mixing Hashirama's meat with his own (i.e. mixing the Indra and Asura chakras) to get the Sage's power. If Naruto did the same by mixing Sasuke's meat with his own, would he get the Rinnegan? Or, if Sasuke mixed Naruto's meat with his own, would he get Rinnegan in both of his eyes?
I guess, if you combine Ashura's and Indra's chakra, you will obtain the ultimate dojutsu (Rinnegan). Since Naruto is a rebirth of Ashura and if he can implant Sasuke's chakra (since  Sasuke is a rebirth of Indra), Naruto probably will obtain the rinnegan.
