your ar-2 board in missile command should (factory) be a -03, and centipede uses a -02. per elektronforge it might work, but someone needs to chime in as to if the transformer brick will work. your trackball should work.
as far as control panels, see if you can find someone with a centipede cocktail and a missile command cocktail, and have them measure. you're gonna have to bondo and drill holes though, i'm sure, if the overall size works.
edit - looking at pics online, the control panels are shorter for centipede. not to mention the opening in the top may not be the right size because you'll have to rotate the monitor. you may just be better trying to find a centipede cocktail.
