This might catch your attention. I started this thread about an idea for 2h weapons, but this could also fit into your idea. I had doctored an image to show a 2h weapon :]

Someone also said he saw this type of weapon type on debug, but I guess it never happened due to that thread is quite old.
I also love your weapon :]
