Hey Mo-Dave, check out this video of a "Red Neck W E. I had the same idea, but would mount one socket holder on each side that could slide in and out to adjust for different edge angles, similar to the WE. Should be able to build one for less than $40 + the lansky. Thought of building it on a poly cutting board.
This is video #1 of 2. The second shows him using it. Should be referenced from the first video.
