This would be an easy mod to make. Lowes and Home Depot both sell various metal brackets with holes. With these brackets you could attach the legs and not disturb the cook chamber. Attaching this way would probably also be stringer and last longer.
So many options to make the station fold out of the way or detachable.
Of course there are other ways to do this. I see this as pretty easy with least amount of work and skill. (not at all implying you dont have skill!!! :) )
