The main concern with wings and flight controls is small disruptions in aerodynamic performance which can have large impacts on lift and stall margin...especially on the 200 without leading edge devices.

The fuselage does not generate lift, so the concern is a little drag and a little weight...the weight of any reasonable snow accumulation would probably be less than the type-IV fluid needed to prevent. If you're within the HOT for whatever conditions exist, you will not have massive sheets of solid ice forming on the fuselage. The motors will be fine.

I'm not worried.
