The photo I attached was of a arbor press with a much deeper throat. The limitation ultimately is the size of the box foldable by either a box pan brake (say 12") or the 3:1 tool which in my case is 30" but they do come smaller. So punching half and then rotating the material by 180 degrees and punching the other half does effectively double the depth. If it came down to needing something larger it could always be fabricated.
