Okay, let's say that Rinnegan is really a separate doujutsu. But even then, Sharingan seems to be necessary for it's awakening. I mean, there wasn't any single person shown to awaken Rinnegan plain from the regular human eyes. Yeah, we were told by Hagoromo that Rinnegan components are Indra chakra + Asura chakra, yet we should look somewhat beyong it. If it's actually so simple, then why didn't person like Naruto manifest it after receiving Hagoromo's chakra? Besides, @Thekillman, the word "prerequisite" is the most fitting here. If you need prerequisite SM to awaken Hagoromo's SPSM, then why it's impossible to need some prerequisite doujutsu like Sharingan to awaken Hagoromo's doujutsu, Rinnegan? I.e. if Rinnegan and Sharingan are different doujutsu, it =/= that the latter is unnecessary to awake the former. And it makes sense for Hagoromo's descendants with doujutsu prowess (Indra and his reincarnates, more specifically) to awake his visual power, Rinnegan, while for Asura and his reincarnates it's more suitable to awaken his body power (i.e. SPSM). Also, I should add that Black Zetsu mainly used Uchiha clan to fulfil his goals (thus Indra manipulated and their tablet rewritten), so it automatically means that most of his hopes were on Indra's reincarnates rather than Asura's.

P.S. Besides, its pretty hard to judge if Madara has lost his MS jutsu with Rinnegan or not since he demonstrated no MS jutsu except for Susanoo (which didn't even require the eyes itselves, as it was seen later) at all, even in his past days still with MS and EMS.
