What I'd really like to do is get a machinist to fabricate a replacement mount that shorts the contacts and has an M42 screw thread rather than the K bayonet, but I expect the cost would be prohibitive.
Why not just modify your existing mount (or maybe one from an old "donor" camera) then "fit and forget" an OEM M42-PK adaptor.
I'll admit to being happy to work in Manual with my 42-screw lenses, so I've not bothered to consider modifying my camera, but my *
ist DS is permanently fitted with an M42-PK adaptor and I treat it just like it was a screw-mount body. Just a pity Pentax never saw fit to enable the auto-stop-down of screw-mount lenses on their bayonet bodies, like Fujica did, so each of my auto-aperture screw-mount lenses that don't have an a/m switch have had to be modified to hold the pin in
