I've had an idea of a City of Sigmar in the realm of fire based around fire beasts with a bunch of scaley cloaks, etc. The idea mashes up a bunch of magmadroths, fyreslayer bits, handgunner bodies, etc.
One of the ideas was for the Freeguild Handgunners to use Auric Hearthguard weapons. Here is the quick mock up. I think it looks quite good, not sure if the scale is right or not though.
