did you see the WoodWhisperer's shop? He has something like a room divider set up that holds his plywoods etc. Not sure what your shop space is like or if this works but you might be able to play with the idea to get a double-service out of it.
Not sure if you can open this (and I know that you don't want wall storage) but for anyone doing research, this might be of interest). I hope it opens for you.
