I appreciate the input but I decided that they just weren't up to snuff anyway. Instead I dug into my reserves and pulled up the 30 beastman gors I had been saving to make a chaos cultist unit out of. Considering the price of the new plastic cultists, I realized this would be a better use.
Below are some straight up Wracks with "bubble heads". I made some additional bubble heads by covering normal heads off the wyches sprue with putty and super glue. Those did come out alright but still need some sanding.
There really isn't much to change besides replacing the heads. 1 out of 5 had a chaos symbol on his belt that was easily covered or filed down. I also did not like the wooden handles on the axes (or the fact they were axes at all), so I cut them down into cleavers which are more wrackish IMO. I also made a neat agonizer out of a Talos spine thing, but I forgot to photo it.
I was debating about filling all of their feet out with green stuff so they didn't have cloven hoofs. I decided instead that I kind of liked them; I mean we are playing Frankenstein (if not god) here anyway. I also really like the thick patches of fur, I think they fill the gnarlskin idea well. The best part of these though is that they are the same size as the other Dark Eldar models, as opposed to the kit-bashed orks which were huge relatively
The previous experiment with the ork bodies though did give me an idea for the liquifier guns. which I'll be using on my new versions. Here is one I might actually keep.
I personally find the idea of firing corrosive fluids from the face/mouth makes much more sense to me. There is a pressure bulb on the other side of the gun you can't see from that angle.
These older gors included 1 large and 1 medium/ body per sprue of 5. I used some of the medium sized ones as Acothysts, and turned the rest of the medium and large into Grotesques. This is actually easier than the wracks since you don't need as many, and the extra talos arms/masks work for these purposes. They do look a little scrawny on the 40mm bases though.
The largest one in the front will be my Abberation, but he is actually from the inquisitor 54mm line of models. He looks just about perfect as a grotesque though IMO. He's huge, but hunched over to the point that he's no taller than the rest. Unfortunately being metal means I couldn't get a picture where he wasn't reflecting the flash.
It makes me sad that only 1 Grotesque per unit gets a liquifier. I need to do some wire and green stuff work on this one but you get the idea.
Anyway, thanks for letting me bounce some ideas off you
