Looks great. Very good craftsmanship. 8)
Did you have a reason for doing this? Changing the number of spokes maybe?

I have always liked high flange hubs, and especially the Schwinn hubs with big holes. There are no high flange coaster brake hubs currently available, so I decided to make my own. I found Amir in Israel who makes flanges for Atom hubs, and he agreed to make these for me. Now I am to the point of testing them out.
That's Kool! Big fan of anything high flange.

Bikeguy and Amir did an outstanding job building this hub. I am working on a production version of this based on my own hub parts with the Velo Steel coaster brake.
Here are a few CAD renderings of the hub:

how cool is that. 
back in the day, when I was into bike racing. I had wheels with Normandy and Campagnolo high flange hubs.
Since the spokes PCD is bigger than the cog. Its easier to fit spokes. Don't need to remove the cog. An advantage when servicing it.
I have an old Shimano 3 speed hub, that's got a chrome plated centre section, and the spoke flanges seem to be pressed onto the hub, and are not chromed. I always thought they could be removed, and high flanges made and pressed on. But making those flanges acurately is beyond me.
Maybe high flanges from disc brake hubs could be modded to fit on there
Maybe Bikeguy should make a better fitting clamp for the coaster brake arm, onto the chain stay tho

The clamp in the picture is not tight, and the bike is only mocked up pre-paint. Velosteel supplies the clamps pre-formed, but they can only guess at what shape your chainstay will be. The person installing the hub needs to shape the clamp to fit the chainstay tightly, of course. I took the picture so show the hub, not to demonstrate the ideal installation technique.
:shock: Wow! That is really nice!

Finally got around to shaping the brake arm clamp. Hopefully this will meet with your approval:
