I never have, but I've done it with a Crown bowl and also a phunnel. You should be able to do it with any kind of bowl, just experiment with it. In my mind, the main thing is to wait for the top layer to sear and allow the bowl to heat up a bit before taking a pull. Then it's just a matter of heat management like any other method.
