The sad thing is, a newbie could totally believe this and try it. While you have this in jest, the actual theory behind it isn't flawed, and in actuality, it's something we do, except we use the tactile feel of the tobacco in between our fingers and the resistance in the bowl to do what you describe. But for us it's just practice. By the way, I'm sure some scientist, in the long history of the pipe, probably did something similar to what you describe.
