Nice, thanks. That's helpful.
And it is too bad these folks are out of print. They had a lot of character.
That said, as far as I can see the biggest issues in building an army are the bears, the lancers, and the (arguably) the war wagons: infantry can be proxied somewhat -- Araby archers come to mind -- a mix of steppe horse archers and HElf reavers would paint up nicely as horse archers, and Axemen can be scrounged.
Actually, thinking about it, one of the biggest challenges is scaling up Pendraken's 'Wings' from their Polish winged lancers -- the winged emblem would do a lot to make, say, Bretonian peasants or spearmen announce themselves as Kislevite.
