You can't rule out one group of people because it disproves your theory. Otsutsuki's awaken Rinnegan without Sharingan. Therefore anyone else can by doing their same method until the series states otherwise. Just because they're Otsutsuki doesn't mean the logic of the Narutoverse doesn't apply to them.

@Elve The page of the wiki makes no mention of that. Care to give an exact page so I can read it myself, I can't find it in Shi no Sho or the Jin no Sho.
