+1. Been waiting for this one myself... A room of displayed armors, like a trophy room, will be excellent. Especially with a line of weapon racks to accompany them... However, at the moment, attempts to spawn Mannequins create a mobile npc that wanders around your house, and you have to manually add items through console. I know that there are a few modders currently working on this, though, so we should see it soon :>
