Both of those options make the construction a bigger challenge, indeed. Hats off to you, buddy. Those are both feats in engineering as well as was building the thing in the first place.
Indeed....
I've been looking at the amazing Death Star Franck is making and I made something similar a year or so ago, it was my first foray into Dirama making. It was a modular system made up of sections that could be stacked in numerous different combinations, the hangar base and side walls were reversable and could turn into the Trench. As a toy it was a great idea, and Hasbro could make a mint making something similar using industrial methods, but in reality, on mine the decals peel off easily and the whole thing is a bit too fragile for everyday play (I have a 4 year old and a seven year old, so anything I make needs to pass the ultimate play test).
It comes out of it's box occasionally but it needs to be stored in the garage as it's so bloody huge, if I left it out, the gloss floors quickly attracted massive amounts of dust. I vowed that if I was going to create anything else, it needed to be tougher and more child friendly, after all, I love making the stuff and taking pictures, but my kids are the ones who play with it all. I think Franck is taking the idea a step further and is certainly making a better job of it in terms of the design. You'll probably see elements of my set used in a forthcoming photonovel.
Here was my Death Star 1:
As a consolation for having to store the playset in the garage I quickly made a miniture hangar bay for my eldest for his bedside shelf.
