Yeah it would explain Momo gaining a forehead Rinnegan after absoring him, and it would also mean that Kinshiki's red chakra ability is his own Rinnegan Specific tech.

edit

Seelentau OR FF-Suzaku translated some early boruto material and I swear I remember it saying two enemies with the Rinnegan not just one. Besides didn't the novel say that it was tradition for the otsutsuki to eat god tree fruit, or chakra edibles from the god tree and then one day their own children will absorb them in the same fashion?? So I'm of the thought that Kinshiki does indeed possess one rinnegan on his forehead.. I would say it is purple too hence Momo's also turning purple.
