That might have worked, but sadly that isn't stated. The manga where that sensing was used by Minato or the Chapter when Tobirama used that same method, nothing about vibrations were ever stated. The wiki also doesn't state it, nor does the Databook. All that is known about their sensing method was that they can detect the total amount of enemies and that Tobirama could go as far as even to tell that Orochimaru's body was made mostly of Hashirama's Chakra. Chapters 239, 481, and 620. Wiki under Sensing. So that won't work since that isn't a stated ability.
