>>6471550I'd pick Philip Reeve's Mortal Engines, maybe as a tie-in with the upcoming film. I first found the series through a Mortal Engines-themed battle on the Brikwars forums, so it'd be neat to have it come full circle. Might be a little too large scale for retail Lego, but Lego has done a lot of Peter Jackson/WETA/Universal stuff before.
