Absolutely impossible really. The whole purpose behind hydrofoil is that it is below the surface and creates minimal drag on the rest of whatever is above it. So you would have to have something running under the snow, which would create more drag regardless of size, it wouldn't work. You would be left with a total failure of time and money, and a device that allowed you to ride on top of something that glided on the surface of snow, so skip that middle section and just ride skis or a snowboard.
