I need help finding a good 15mm scale set of mini to match Runewars. I want to replace a few of the beasts for more suitable figures.

I am prentending that at the current time in Runewars, Orcs and Dwarves had a huge war that left both crippled and with very low population. This gives reason to why they don't have home realms anymore. The orcs that have lived in the wild are now more savage and take the place of beastmen minis. The dwarves are a dying race but toughened. I figure If I can get a good dwarven rune priest or something in a 15 mm scale it could replace the sorcerer minis and still fit the mechanics. I would like to replace the hellhound and razorwing also. Trying to add maybe a cat warrior riding a wildcat, to replace the hellhound and just have the buring ability represented by the hunting skill of the cat warrior. Finally I wan't to replace razorwing with a flying mounted warrior.

Let me know if you guys can think of good minis for this. Please provide links if you can.
