I think that is possible, but it would take many years, Sharingan is low powered version of Rinnegan in Indra's descendants and Asura's descendants have Sage's bodies, if the chakra of Indra and Asura reincarnations is combined they will gain Hagoromo's eyes and Sage's bodies, but that chakra would take more time to amplify. It took Madara years to awaken Rinnegan it would take more than that for Asura's incarnates because their eyes are less susceptible to change unlike Sharingan. Naruto's eye changes when Kurama takes control over him, if he is in Sage Mode he will have toad eyes because of Senjutsu chakra, his eyes change due to chakra and because of that I think there is a possibility. The best way would be to steal Sharingan of Indra's reincarnation.
