I've been wanting one of those Swamp horrors for quite some time now for my Dark Eldar, proxying as a pain engine. Would they work as a relative match in size? Or are there any similiar figs out there, perhaps not in metal? The biggest drawback for me is that the swamp horror's not in plastic :/
As a side tangent I'd really love to have Lokhir fellheart as an Archon (why is he still in metal!)
