Not sure about the future form factor, but one solution in the interim might be to replace the metal mud ring with a plastic one, unless there is some reason your local code requires a metal one. The problem is, which I’m sure you’re aware of, is that it may take some surgery to get it out.
Carlon makes a plastic mud ring that might work better. I haven’t tried them, however. Since they’re plastic, they might be easier to modify with a rotary tool if surgery is required.
