I was looking at the lusid plans when I built my cab, but ended up working from the elvis plans instead. I only wanted 2 sticks, 6 buttons per player, and credit/start buttons. They fit comfortably into a 60cm wide control panel (23.6") so you shouldn't have any problem making lusid's panel smaller. I believe the lusid design is 26" wide, so you could make it without any overhang.
