I'm interested, I saw your work for the "Super Jup" and it was impressive! Are you thinking of something where we remove the Neptunes from their cubes and mount them on your base, plus associated plates and pieces? Or, are you going even further and thinking of a rackmount unit of some kind 
Case1:
I don't think so. It's only an needless try to get out more of this machines. But it will not be possible, because you can't

Case 3:
narrowness
Most cases 1 and 3 together
