Kallistra and Pendraken offer lots of options here. The Kallistra fantasy ranges are based on the Pendraken figures, but cast on strips.
Pendraken offer two dwarf ranges, Dwarves and Hill Dwarves. The Dwarves are older, and a bit more of a caricature, big bodies, small legs. The Hill Dwarves are probably more similar to the GW figures in size.
