As crazy it may sound. I think its possible for naruto to get or rather activate rinnengan.
1st comparing with Nagato both of same clan. Also Naruto may trigger and awaken Rinnengan when Naruto feels the pain of losing some1 he loves just like Nagato.
2nd comparing with Sage of six paths: Naruto got a bijju. And has also develop similar symbols when in his new mode.
Also cuz Rinnengan isnt comon eye unlike sharingan & byakugan of same clan. Formation of rinnengan is rather unique and who better to get than Naruto.
