Hey Warchild,
We have several furniture "placeables" that are indeed taxodermic in nature! No orcs, but I think we have dear, boar, bear .. I cannot remember off the top of my head, but there are a couple of options. And if you were willing to play pretend we also have a quill system that allows you to rename and modify the descriptions of housing placeables. It wouldn't look like an orc head, but you could describe it as such.
