@Superinu you are wrong only ashura and Indra incarnates can awaken the rinnegan both obito and negato were using Madara's eye (the only two ppl to awaken rinnegan other than an otsuki were Indra incarnate sasuke and Madara). I agree that it can work both ways but by a slightly different process. Ashura has the SOSP body so he needs the eyes i.e. The eyes of Indra incarnate needs to be transplanted, Indra has the eyes and need the body/cells to awaken the rinnegan, maybe it can work if ashura's incarnate receives Indra's incatnate cells, but I think the eye transplant is more probable.

And momoshiki was an otsuki just like the SOSP path and kayuga the rinnegan originated with them and not the other way around. It seems like where ever they are from and whatever clan they belong to, the rinnegan is not uncommon.
