Attached is what I could come up with in an hour. In hindsight, I could still put the sprockets wherever I wanted -- either in the box tubing or next to the wheel -- and maintain the constraints above.
The middle wheel isn't shown because it's dependent upon the attached gearbox. The gearbox would attach using a slightly modified wheel block (though still 2x1). I also didn't add in the 3/16" spacer to drop the center wheel.
Maybe more to come after the dog park.

I know I probably sound like a desperate salesman now, but that frame looks like substantially more work than a proper west coast drive. A wcd doesn't NEED CNCing or anything fancy, 973 ran a very, very, very simple and reliable wcd for four consecutive seasons before my time.
I'm not tooting my own horn either, we've made some tweaks and optimizations, but it's really NOT our design. We just love it so much, and despite our best efforts, haven't really found a way to improve it!
