Grimstonefire:
I would be interested to see what people came up with. Obviously it couldn’t be based on GW plastics, and it couldn’t be sold ‘together’ with the dwarf parts (in any shape or form).
Assuming these were to be used with the GW dwarf parts you’d need to have seperate variant torsos for the warrior and quarreller sprues, as they don’t fit each other perfectly.
Check out this thread for what we discussed a while back:

If they were for sale (even non profit), people would be unwise to connect ‘chaos dwarfs’ or ‘dwarfs of chaos’ 
in any way shape or form with them.
