Looking at the design of the lens, it would be unwise to clamp a tripod collar round it.
Thing is, I can't really see how much you would benefit from one. If you clamped it round the area with the distance window then the way these collar are would put the lens support under the focus ring. Hang a camera off the back and you get a rear heavy setup there.
As Paul said, looking at a longer dovetail type plate mounted along the lens axis from the camera would be a better option. Allows you to balance perfectly.
