To my opinion you add correctly that it is about the restistence of the air and aerodynamics (drag). But drag (air resistance) is about surface. (This is why the same piece of paper that makes a folded aeroplane, falls much faster when being crumbled to a gag). So smaller people (in body surface) should have some advantage going down hill. In that respect big people have some disavantage and are rightly put in front of a peloton to keep others out of the wind before climbing starts.
What could count is that heavy people have more muscle power - they would need this if they want to climb up just as fast as the mountaingoats. And that this could lead to a relative advantage going down (when their muscles do not have to carry the weight), they could profit from their power. By adding some extra acceleration.
What I do not know is what exactly the downforce of the weight via the tires on the road does. One could reason that heavy people have some advantage because they are better sticked to the road (so they would not fear going a bit faster - if they would be able to accelerate a bit more). If the road however would have sharp corners, they have a higher risk to end up in a ravine, so they would have some disadvantage because of having to slow down to fight inertia
My conclusion: I think one generally sees that the best down-hillers are very good and daring in taking earodyamic positions and that this is the most important thing. Smaller would help. To my feeling/expectations, it would help as well if they are a bit more heavy - probably because of the muscles and/or the downforce on the road. ( I am thinking of Alberto Tomba).
