Before you go to extremes here let me suggest you do a second sweep of control panels on the eBay.  When I was doing my pac-man cab I first searched for "pac-man control panel" and the cheapest one was around 80 bucks plus shipping.  Then I just searched for "control panel" and visually inspected every panel on eBay.  Found a sky shark conversion panel for 20 bucks shipping included.  Long story short, horrible conversions are your friend.
