since you can't really make random dwarven cities since they had few very large and concentrated population centers their "halls" you could make places like erabor(the kingdom under the mountain) instanced where you enter through some large pre-generated entrance into another dimension called something like "The dwarf realms" or something. By doing this you could make these places truly massive because I personally don't think that the near infinite tunnels and mines the dwarves dug can be done justice by limmiting it to below the biome Erabor (just does'nt seem big enough) - by making it another dimension you could also somehow connect the different dwarven halls within theis dimension. ( a bit like a underground dimension). I don't know exactly how the middle earth version of dwarves did this but the dwarves of warhammer connected all their major halls by the underway's ( if this is not cannon ignore this suggestion)
