Safe to use pancake batter in a pizzelle iron?

My mother went out and bought a pizzelle maker (long story). I've always been a sourdough baker, so the thought of combining these two intrigues me somewhat. I'm thinking of trying my sourdough pancakes in the iron, but I read on another site that it would "fudge up the pizzelle press". I'm wiling to test it as long as it isn't going to damage a $50 piece of equipment, so has anyone tried this?
