Wow, now that's an interesting problem. One thing you could try is to put a filter on the crankcase pipe coming into the air cleaner.

If that doesn't work, perhaps the best approach is to wax up that plate so slick that ice won't stick to it.

Or, you could just pull off the air intake hose and let the thing breath the slightly warmer engine compartment air......Block off the radiator with cardboard, and that will help even more.
