I love the set, (won't buy it but I love it). Now LEGO, hows about you give us a Daily Planet, Titan's Tower, and Hall of Justice for once instead of Wayne Manor (again) and other Bat stuff?!? Pretty Please?!?
I always thought that Titans Tower would be the easiest to MOC. I managed a small one (mirco figure scale) for Edinburgh Comic Con this year and figured it would be simple to scale up to Minifig scale. The biggest issue would be the support for the wings of the T.
