It's a snap to switch between formats. I don't think it would work with a machine that requires a different length cone for each format.
I use a similar set up and it works well. If I were to use a 50mm or 90mm lens for 4"x5" the enlarger head would have to go through the easel. If I used the 135mm for 35mm film, the enlarge head would go through the ceiling.
