I wanted a little more variety in my Chaos Cultist and Mutant stands so I've been doing weapon swaps between the two models. I'm nearly done, the last bit will be to convert Cultists with both Beastmen weapons and vice versa.
I'm also kicking around ideas for heavy weapon cultists. One Heavy Stubber and one panzerfaust-esque model. Nothing to show yet for them.
I also painted up some more Union infantry. Six strips took me about 3 hours, which isn't horrible for me.
