thought i'd give it a try, didn't realise how much work it would be. someone else tried it a couple months ago and they gave up almost instantly. so far i've made madotsuki's bedroom, the nexus, numbers world (first door clockwise in the nexus) and one secret location that you'll have to find for yourself! here's da link:https://mega.nz/#!AUoGRDSB!BD3s54HouT03Rs-mtXLxi9mOWVPGqgBH3AtU4REQfE4
just copy the folder contained inside you your user/yourstupidname/appdata/roaming/.minecraft/saves folder. if you're familliar with the numbers world already, you'l have an easy time finding the secrets. post here if you manage to find them.
