I do have some of them, and they are very nice, but I doubt we will see anything more from copplestone, at least not for a long time. All they have currently are spearmen and axe men, so unfortunately without any ranged troops its difficult to outfit a 'proper' little warband.
I have had a look at Splintered lights dwarves, they're cute and all, but I'd like something that looked a little serious.
Personally Dwarves similar the ones in the hobbit/lotr (I.E not an overly ridiculous amount of facial/head hair on ALL of them and knees) would be brilliant. Some in more unique sets of armour as Mercenaries, or different city states, as opposed to just stunted vikings would be brilliant.
