I know I was against it, but look at the Snake Sage from the canon series. He was a fucking dragon, so there's proof that in the naruverse, dragons exist. I know it was for an entirely different type of sage, but that's where creativity of the rper comes into play.

Not really. The Great Snake Sage was a white snake. As such, the snake sage is just that, a sage. Kabuto's hubris caused him to call himself a dragon. He felt that his ability to continuously absorb nature chakra (and thus his ability to stay as a sage forever) meant that he surpassed the limitations of a snake, and became immortal. An immortal snake is a dragon.
