Not quite sure what you mean or how you really are wanting to mount your light up in terms of how its positioned on the rail, but the DD positioning is pretty natural to me and not at all "a ways away from the rail." You might try a Google search the DD mount in "Images" to see if you can't find some quality pics of it mounted up, light attached, to relieve any of your concerns. If you want the light ON THE RAIL, and NOT offset, then the above suggestion about a simple 1" ring that you can choose the "ring height" on to get it exactly the distance "off the rail" you want is probably easiest.
