A well reasoned approach.

The cone looks great.

I am thinking that a lathe-less approach might be to use lens multiple boards. Clunky looking top hats could sand in for that smooth looking cone. With no front movements, vignetting shouldn't be an issue. Maybe a recessed board could work for a little 90mm 6.8 too.

Thanks. It was originally intended for a 75mm swd which would have used a flat board. The hole in the front is large enough to pass the rear group. I made a cone but you can just as well make it a cube. Or a sliding box camera with some fixed positions. Depends on the materials you have at hand and the tools you feel confident with.
