Alright, I've made some progress.
Sorry for another crappy cell phone pic, but it's what I've got right now.
As you can see, I'm still short some weapons, and there is considerable work left to be done with greenstuff, but progress is being made. I have worked out which heads to use with which bodies (mostly Daemonettes, with a couple metal Amazons, and an old DE Jetbiker), and started putting parts together a little.
Next up is basing them and molding boots to cover their old Daemonette feet.
