I think that the figure 8 design would work well. I would probably use a rescue eight made out of stainless rather than an aluminum rappelling eight. With a rescue 8 the line won't slide up the side and accidentally girth hitch on it. I would be concerned about the loads. Typically, the loads while rappelling are quite light. There is no snap loading just a gentle descent. The loads on a gybing main could be much bigger, especially if it snap loads. The figure 8 idea would probably be fine on a small boat but any main with a 4:1 mainsheet purchase will probably overload a descender (figure 8) pretty quickly.
