Mythbusters said it couldn't be done with the arrows they probably used back in the Crusades. They didn't say it couldn't be done at all though. They actually showed it being done with modern arrows on the revisited episode of it; but the actual myth they were going after was dealing with the arrows that historians mostly agree on that would have been used in the actual time frame of Robin Hood had he actually lived and been around.
Back on topic now...yeah that's the expensive way of doing it. It's always better when you're in a 3D shoot and do it to somebody else haha
