You don't mention how it'd go well in Distortion world. How would it allow for trees and rocks to appear and disappear. It wont work for the moving platforms, nor will it allow you to walk on walls, which is one of the main aspects of this place.
For trees and rocks disappearing, my idea was to do something similar to what was at spawn. Anyone rember the blocks that just appeared and disapeared at spawn? Maybe we can do something like that on a larger scale. I know that SethBling has some other videos that can help us with the Distortion World. However, I do not know how a player can walk on walls. There are mods to do that, but I don't know of any plugins. Maybe we can create one?
There is a anti gravity mod that has a little platform that you can place on walls and ceilings that let you walk on them so that might be handy
