If Enderman are not going to be implemented into new Galacticraft update why not make them intelligent? As a sort of late-game or super hostile planet, the Evolved Enderman that purposely grief you if you look at them, something like detecting placed leaf blocks/machines and taking them away to an Enderman den/dungeon(where there could be an Enderman boss could guard your stuff) and makes it more difficult to have a completely self sustaining station since you would have to adventure and take your stolen equipment back and possibly find some new loot in Enderman dungeons to make things more challenging.
