I think that in order to get the Rinnegan Naruto would need Six Paths Yin Chakra and to get Sage chakra Sasuke would need Six Paths Yang Chakra. However, going by Hagoromo's example, it seems that one can acquire the other power on their own. It's never explained whether Hamura did so too (and whether that was the reason he got Tenseigan).
