Glad to hear you like it and are trying it. If you have any questions or problems, I am here. Please do let me know how it turns out.
A round post would surely work and others have done this. But it does not provide the re-indexing that the D shape does. With that plus the height adjustment screw, you get repeatable positioning well within a thousanth when you remove and replace the holder.
I have also used 1/4" tools in mine and the adjustment screw eliminates the need for shims.

Make it fit.
You can't win and there is a penalty for trying!
