Be extremely careful with this idea. Micro-racks are not designed to use anything less than all four bars. In fact, with each of the designs I have seen, a three bar descent is impossible anyway. Disengaging the bottom bar will automatically cause the third bar to drop, putting you on two (effectively zero) bars. For this reason caution is important when feeding rope on a slow rappel. Pushing rope up from below can allow accidental disengagement of the bottom bar and disaster.
