@artifice, I'm not sure if it's that far fetched, after all, isn't the same thing happening to the 6 Paths of Pain/Tobi ? Ninja with normal eyes, gain special Doujutsu and some jutsu associated with it (Pain's paths), thanks to some chakra imprinting or something. The normal eyes obtain, by special chakra coursing through them, the same or part of the power that the user with the original eyes posses.

One could say, that the normal eyes become a reflection of the eyes that reflect the power ?
