Rohloff Shifters for Drop/Curved Bars

Does anyone know if the Tune or Rewel Ti shifters for the Rohloff will slip on to curved bars, or if there are any others that will? (The Toxoholics seemingly won't, though if anyone knows differently I'd love to hear it.)

I know the Mittelmeyer unit is made for this, but curious what else is out there that I might be able to make work on a Black Sheep mountain moustache or integrated moustache bar/stem unit a la the recent NAHBS winner.
