The Uchiha may have Indra's Sharingan chakra/genes, but i'm sure there is much more to Indra's chakra than his eyes, they are just fragment of it. Oh i very much agree with you. But Rinnegan is a fragment of Hagoromo's power just as Sharingan is a fragment of Indra's. Therefore, you do not need to be a Transmigrant to awaken it, as long as you have the right fragments of transmigrancy. These fragments must be fairly plentiful to allow transmigrancy of largely unrelated people, which makes sense considering the large amount of Uchiha and Senju that once existed.

So, you don't need to be a Transmigrant to awaken rinnegan, your chance are just much lower
