god lord... and I thought the kids would stay in the construction server (no offense. if you read this, you are no kid because kids don't visit this forum)
Back to topic: I already wanted to import Minecraft meshes into UED, but atm I have another project running.. looks like someone took over the idea and made something out of it.
Things that might be done: Add the monsters to invasion

Add the mechanics of the... 'electrical system' (glowstick and wire) for mappers
and last but not least: create map which actually looks like the natural environment of minecraft.. instead of a hovering hellbenderrace track.
