I compiled a bunch of notes I made for a HoE minis game awhile back. What I had put together was a lot more like GW's Necromunda than GRW. But then Savage Worlds was announced, so I figured I'd wait until that came out before I did anything with it. Having seen the text of SW, I can say that it'd be simple to do a HoE minis game using that, with source material from The Unity adventure.
