Nope. That's not how a Rinnegan works. Rinnrgan works completely different compared to all other eyes throughout the franchise. For Rinnegan, you simply need the Chakra of Asura and Indra. An Indra Reincarnate can acquire Rinnegan by gaining Asura's Chakra. An Asura reincarnate can acquire Rinnegan upon getting Indra's Chakra. Basically, Asura's and Indra's Chakra are the top most necessities for awakening Rinnegan. Even a fodder can awaken Rinnegan if he's given Asura's and Indra's Chakra.
