Unless its mistranslated, Kabuto said that his hypothesis was correct. Having recreate or obtain Hagoromos chakra does not invalidate that the Sharingan (or at least an Uchiha eye) gets moved up to Rinnegan.

Both people to unlock the Rinnegan after Hagoromo both had Uchiha eyes and 2 people to recieve his power later who did not have Uchiha eyes didnt get a Rinnegan.

Even if the Sharingan isnt a pre-req, at the very least an Uchiha eye is. Basically 2 for 2 on that one. And this would make sense because Indra and his line obtained the special eyes. The Rinnegan is locked in the Uchiha eye and Hagoromo's chakra acts as the key.

Unless you are saying any shmuck that gets Hagoromos chakra gets a Rinnegan and 6PSM. But the hole in this theory comes when Madara did not get 6PSM and Ashura had no Rinnegan.
