Looking at the yoke on my Jedi, it is already... 80% the volume of what I think of as the smaller bartops, so I expect you're going with/looking for a larger "bartop"?
Thinking on what compromises I'd make if I couldn't have a fullsize cabinet, I think I'd look at either something like the Pin-Up project, or a pedestal (with the HDMI dropcord to the bigscreen), but one of those large bar-tops like the SNK, which use their own pedestal, would be considered as well.
I've perused a lot of bartop designs, and most fall into the sloped-back style followed by mini-but-looks-like-a-big-classic-cabinet style. The Upright ROTJ already looks like it's on a pedestal to some degree, so creating a looks-similar mini starwars cab should be doable.
