It would still need to be in a location and with a mounting system to insure it breaks free from the main body of the wreck if it's under water. A pinger with a 30-day power supply is probably considered more practical.
Or a much louder pinger. With the Malaysian flight, appearently the pinger was too weak to have been audible at sufficient distance to ensure it would be heard clearly and located before it's batteries ran out.
