I know, I know... this is sooo wrong since they are some of the nicest models out there for dark eldar. And many people don't like to use mandrakes in their amry due to the rules and how they interact with 6th edition. But hear me out.
I have a dozen or so of the old metal daemonettes of slaanesh... and I was looking at them and realized with very little conversion (some green stuff over the mouth and lower face to start with) they would make very interesting mandrakes. Mix them in with the standard mandrakes and it would look like a really vicious squad I think.
I am in the middle of working on various other conversions for my Haemonculii coven (has a strong wyche cult tie in, with alot of the old metal wyche figures and the dark elf witch figures... *snicker* even have some of the old metal mandrakes in my wyche cult) and was looking at my parts and old figures I never assembled and came across the daemonettes.
I would love to hear some peoples opinions on this... I will likely make one up and post a picture on here later of it.
