There's nothing wrong with a goose, per se, but yes, I'd say just wait until you get your pipes. Besides, once you have your pipes, you can cork the drones off at the stock and use either a lot of hemp, or an adaptor, to make a goose with your practice chanter and pipe bag, if you want to.

I had a fairly traditional piping education, and I can't recall that I ever used a goose.
