As already mentioned on @Glyphiks thread, we had the same brilliantly stupid idea to create a puck shell that turns it into a trigger remote.
So far, I have re-built the puck guts casing, added a trigger to the thumb wheel, and mocked up a pistol grip to the back shell
Next step is working on the ergonomics by adapting the angle of the trigger and of course deciding on how to best adapt the puck guts shell for a better look and feel.
