It's a little known story, but there used to be 80+ people working on dwarf fortress years ago. One of them came up with a plan very similar to yours. However, when things didn't work out and he wasn't able to pull it off he went mad. He ended up killing a secretary with a plastic plant, cutting himself with a shard from a glass which was knocked off the table. He went back to his cubicle where he bled to death. The rest of the staff arrived later and upon seeing this also went mad. Only the two brothers survived because someone accidentally built the cube walls so their area no longer connected to the rest of the office and they never found out about it. They toil away on it to this day.
