I've noticed a few topics at The Gear Page where people use links from bicycle chains (flat, dogbone-shaped, a hole at each wide end) to mount pedals. Bolts are removed from either two or four corners of the pedal, and then replaced with the link mounted and extending beyond the edge of the pedal.
Then, when one knows where one want to mount it on the board, the extending ends are pinned down with screws into the pedalboard surface.
Manufacturers will often mount gear like this for NAMM and other trade shows, as it doesn't require putting adhesive on the bottom of the pedal, and prevents product walk-off.
If one is going for brute-force elegance, just remounting those Gorm slats slightly wider, adding the removable legs for the board slant, and using the bike chain attachments seems like it would be fairly easy... although not having looked at one of these Gorm shelves in person, I don't know how much space is underneath.
How deep is that space? Can one put a power supply underneath easily without building up the sides/end?
