So what you say imply is that Hagoromo might have been the originator of what made the Sharingan into Rinnegan? Not sure how plausible that is for him to have had an eye superior to that of his mother (who was labeled as stronger) and the Shinju itself. Also logic has it that I'm right, since your story proposes 2 forms of Sharingan with one just happening to look identical to a form of Rinnegan. Like if that ever made sense.
