Mmm are we forgeting this again ? Just in case you don´t remember :

Asura´s chakra + Indra´s chakra + Sharingan = rinnegan

I question to you, how would an Uchiha know who is the reincarnation of either of the Sage´s sons in order to get their chakras and therefore get the Rinnegan ? As far as i know to awaken the rinnegan it only needs asura + indra's chakra in other words hogoromo's chakra to awaken it just like in case of sasuke to awaken it.It was stated by black zetsu and hogoromo himself.Madara added that it also the DNA of two sons(reincarnation) to awaken it just like on his case.Black Zetsu also stated that he choose the Indra's reincarnation to awaken it because the uchiha clan is prone on emotions and they are easy to handle and happens that the Hogoromo's tablet was in their possession.

Sharingan was only a ability just like senju/uzumaki's healing power and strong life force,as we know all characteristic,ability and other specific features was lies in their genes/DNA which means when we steal it and infuse it to ourselves,we have a chance to replicate it.It is proven when Jugo, Karin and Suigetsu's abilities was able to replicate by Kabuto when he infuse their genes/DNA ob his own same case with Shin uchiha when the uchina DNA was mutate on his body and he was able to replicate it forming a too many sharingan on his body.
