There'd have to be "truth" gait data for the person. Gait is highly variable between subjects, and if the weapon is worn in a centered position (small of the back is a common concealment position), it's unlikely this will work. Holsters are not always worn in the lower extremities, either. I'm not sure this would be all that successful. It seems quite difficult.
