Need to see more of how that part of the game is constructed for how hard/easy it will be to impliment... but something about that portal lane/shot/garage, how it is laid out, almost seems like the idea I have in my head is something like what might have been planned at some point in concept/design. Looks like it would fit almost toooo well!
Could understand it being cut due to its potential to blow out the BOM. If it could work the way I imagine, it would look spectacular! ... on re-entry perhaps as well!
Might require the nullifying of a couple of Scotts gazillion RGB lights though! 
Q: I assume if you make a shot to the Unlit portal, that the ball still emerges from the re-entry?
Also watching closer, it looks to me like that is more than just a space ship on a spring... does anyone else think that looks like it is animated by a coil or something from below?
