Hopefully my new Blood Pact army can change some of that.
Here's their leader, who'll get Heroic Senior Officer stats:
I used the Forgeworld Renegade Militia Commander with a couple of simple conversions. I added a small nose and lines on either side of his mouth so that I could paint his face like an iron grotesque (mask) that is common to the Blood Pact. The chainsword usually embedded in his arm was swapped out for a power sword, so much better for slicing through power armor.
I don't have him on a base yet as I'm still working out exactly what style base I'm going to use. It'll probably be an urban wreckage style, but I'll have to do something suitably "heroic" for this guy.
