True but that doesn't mean that just anybody with the Sharingan can awaken the Rinnegan. When it was stated that Naruto and Sasuke were transmigrants, the sage pointed out that Asura & Indra's chakras were clinging to them, explaining why mixing two would result in Hagoromo's own. For any other non-transmigrant Uchiha without Indra's chakra clinging to them, even if they did receive Ashura's chakra it would certainly boost their abilities, but not make the Rinnegan. See Obito examples above. See Danzo (who also had transmigrant Hashirama's cells) and his 11 sharingan for what could've been close to a decade. It was also stated that Zetsu manipulated the reincarnates trying to make the Rinnegan w/o success. While this is kind of open ended, it would imply that it takes more than just anybody to make the Rinnegan.
