can anybody help me with a night fury (how to train your dragon) like draconic steed

[Sidran7e]

Looking everywhere for a Pathfinder rendition of a night fury. I am interested in using the stats for a mount for Dragon Riders in my setting.

Why not slap blue half-dragon template on a griffon, and then give it a sprint ability something like a cheetah's for its flight?
