And now for something you didn't ask for...
I've seen a few people use these homemade jobbies at trade shows for showing four basses. They took two pieces of plywood and cut a slot the thickness of the plywood halfway down the center of the length of each. Slid them together to make an X, stood it up, and voila! Four basses, one facing into each corner. Apply stylistic embellishments as desired.
I googled around for an image, no such luck. There are plenty of images out there of the type you described that you should be able to draw from though.
Tele, maybe you have too many basses? Nah, what was I thinking?
