I've heard of something done similarly... but a little different. The top of the bench had a layer with dovetail slots cut into it; and each piece of equipment was mounted on a dovetail piece. So they could slide into whichever place. Moreover, dovetail blanks were made to fill any unused slot to preserve the bench top.
Myself, I'm still clamping gear to the dining room table of our apartment. I can't wait to get my own space!!
