I have a feeling the answer to this would be no, but here is the scenario.
An existing installation of a 60a pin and sleeve connector mounted to a backbox needs to be changed to a 50a CS twistlock (supplied with 50a breaker of course). It is not feasible to remove the backbox and replace with a FS box for the 50a twistlock. The proposal was to laser cut a piece of 12ga steel to fit onto the pin and sleeve backbox, with holes for the 50a CS twistlock which would then be installed into the piece of steel with the proper cover for 50a CS twistlock on the outside of it.
It would be perfect functionally and asthetically with zero hazard (plenty of room in the backbox, grounding would be proper, etc)
