Hi Ed,
Maybe something like this below could be made in the future?
It would need to be hollowed out enough to clear the thumb screw, and then you could run and end mill around the top of the stop to recess it in, then either screw it or loctite it it in.
The rear corners or my drawing would need to be rounded off to suit the end mill radius.
Aluminium would do the job and be easy to work with and then painted the same colour, which would make it look like it was a part of it.
I saved pictures of your stop on my computer to build one just like it, so will have to look into a slight change of design.

Edit, forgot to add a picture
Now it was to big
