I'm really REALLY curious to see what (if any) way you'll incorporate Hasbro's Freeze Chamber set.
I really enjoyed it, and still am figuring a way to make a bigger gantry thing that just snaps on over its current one. The only thing that set lacked was it being able to hold more figures I thought.
I first sketched an idea for a Bespin display back in 2000 (long before I'd ever even heard of NiubNiub, I think I'd seen StarConstrux by then but there was no clue given as to how to go about building
something like that) but I dropped the idea once I heard the Hasbro Freeze Chamber was going to be made. It was great for what it was, and I've really enjoyed a nice little display on it.
That said, it is just too miniaturized to work in my playset, and I'm just going to have to scratch build my own. I did pick up two spares back when the fan club clearanced 'em, but other than chopping out the steps from them for my walkways, I've never figured out how to use them.
On the Death Star I used the Detention Block pretty much as a whole, and on my upcoming Endor Playset I intend to use the POTF2 Bunker, but I don't think the Freeze Chamber is going to make the cut, except as fodder for set dressing.
Too bad, because I've always really liked it.
