The lens board isn't reversible, and if the lens was mounted on a flat board it would be impossible to focus. But the lens board doesn't have to be as deep as this one, it could perhaps be 1.5 - 2 cm shallower (I have tested). I have a feeling that lens boards for this enlarger are hard to come by, but I suppose I could get someone to make one.
I have attached a photo to illustrate how it's mounted.
