He suggested that I go with a modular design instead, particularly since I couldn't find any wheels that I feel would work properly. Thus, today, I constructed this:

From what I can tell, based on this design, I might have a winner. It slides really smoothly, particularly if I use it with different height ends, thus allowing gravity to assist with the movement. I get the 5D tomorrow so we'll see how it goes. I've also ensured that I can mount the camera from above and below. I've also cannibalised my tripod so that it can be mounted on multiple things using the proper head.
