The Vertical Slum in Dungeon World

Just read this article on this resource I happen to have! I've been curious how to make D&D or other systems feel fresh and new. I'm also curious about digging into it in conjunction with +Dungeon World, a 2d6 system based on Powered by the Apocalypse that is very new player friendly. Thoughts? http://www.enworld.org/forum/content.php?4799-Scaling-The-Walls-of-The-Gathox-Vertical-Slum#.Wk_tPVQ-dQI
