They have the sharingan which is directly Indra's chakra, especially in the case of Itachi. I understand that it might have taken much more time than it did for Madara since he was the actual reincarnation, but if they could survive for the time it would take, would it be possible? I don't think so. Yes, possibly every Sharingan contains Indra's chakra, but only his direct reincarnate has suitable chakra to develop the Rinnegan cause his chakra is the closest one to Indra's chakra. For example: Obito had both MS and Hashi's cells (which made up even the half of his body), both were perfectly under his control, yet nothing suggests he could've awakened the Rinnegan. That's why I think only reincarnate is able to accomplish that, with the help of the opposite reincarnate's chakra.
