Also.. Hashirama obviously did not have Dojutsu, yet Black Zetsu was trying to get him to awaken the Rinnegan too as Black Zetsu said himself. So in short you don't need a Dojutsu from the start.. you would just awaken it as if you were an Uchiha awakening the Sharingan for the first time. You are forgetting that once the reincarnate dies the transmigration ends. Hashirama didn't have Ashura's chakra anymore lol A non uchiha cannot awaken a sharingan nor a rinnegan. Black zetsu was dedicated more to the uchiha because its easier for them cause they have the dojutsu and all they need is a piece of body from the other reincarnate. For those with the body reincarnate, they need the eyes lol. Awakening dojustus are exclusively uchiha.
