I seriously doubt that would work. The big hat BC torsos are only roughly regular dwarf in size whereas the torsos of the Dragon Ogres are ogre-sized so the lower bodies would be much too big for the smaller BC torsos.
I actually think the dragon ogre torso’s look much better than the dragon part of their bodies. I’ve been thinking about putting their torsos on juggernaut bodies, but went for the regular, cheaper ogres.
I would be curious to see a big hat inspired sculpt in the scale of the current BC. The old ones arent bad just tiny. would be neat to see them bigger.
