I've owned that grill before and considered doing the same thing but went a different route. The idea I toyed with was to cut down the front sheet metal that the regulator, igniter, and flip-up cover mount to, just to keep all of those pieces intact and in similar proximity with their stock attachment methods. The goal was to have a smaller, cleaner piece of sheet metal that could then be trimmed out in wood and mounted to the wooden table somehow. I never went through with it though.
Sounds like a fun project!
