You could slap some wings onto the DK form you use.
Also, it's client sided, not server sided, so, only you'll see it, blah blah etc.
I've not checked out a DK form, but, I'll assume its the same as the pally one, and it's just an outright model, which, means you can do whatever you want to it.
If you want to pally up into SSJ3 Goku, you go right ahead. All you need to do is edit the model :3
As for your question, you would need to have a model of Cichol. The other file, the .xml is purely for the effects, like, pallys do that Glowy thing, and DKs have the eyes.
Model of Cichol is in Gfx>char>human>morrighan.
Enjoy ^_^
