Ha ha! I looove this style of cab, mostly because we've got heaps of 'em here in OZ... I scored one a while back with plans to change the vertical controls to a more wrist friendly angle. I've done most of the major structural stuff... the new control boxes are also detachable so player 2 can jump round to player 1's side & kick his ass at Street Fighter!
I put a slightly larger screen in too. As well as dominating my memories of arcade machines, this style takes up less room than other types of cocktails I have seen... but that also means less room for all the computer parts you've gotta fit. Unless you've got a particular affinity to 'em there's probably easier options...
Does the current stick (two-way I assume?) use the standard wico pattern?
