I think i would actually work. I don't have my CAD with right now so don't quote me on this, but our drive used our own custom press hubs for the 3.5" Colson wheels. Looking at WCP, the OD for the dead axel hub press is 1.2" OD which is close to what we used, I think we did 1.1" because the wheel begins to taper at 1.2" so we made is smaller for weight, aesthetics and using the wider part of the hub as a stop. So if you machine the wheel to 1.2" all you need is a washer or don't press the hub all the way into the wheel. There should be enough material for it to work even if it is tapered at that section of the wheel.
