That's tough, I'd test that idea before doing it. When the snow gets deep on the lake, the weight of the snow pushes so hard on the ice. Flooding often occurs. If you shovel down, drill the holes and set the shelters, you may end up fishing in several inches of water. Shelter flaps laying in slush, they freeze down, then you are trying to get your shelter free with a chipper, trying hard to not rip the flaps.
