Commander Vyper, you and I are thinking on the same wave length here! I have been converting GW flagelettes by using Cadian arms and boots, and puttying on hoods and rags. But these are perfect and will save a lot of work. I was just thinking at work today how the flagelette heads would work with these, especially the bare head with his mouth sewn close...
This will put me much closer to finishing The Sundered, a cultist Armor Company. Hopefully some Feral special/heavy weapon troops will follow!
