Looking at the Miniature Market black Friday sale I was checking out the Wrath of Kings miniatures. They have the House Goritsi - Skorza Box #1 on sale right now. For those unfamiliar as I was they are a wolves faction for that game. Would make good Varkaanan alternates, while they are all unpainted so would take a little bit of effort. MM's site pic only shows the heroes in the box but their site also shows the Skirmishers.
Also the honor and trechery box which would make a good alternates for the quickblades and the three heroes. The Ashmen could make a good use for more cultists or Ebon Armor or Knights of Blackguard though they have a samurai look of them.
There is also the Skorza starter box which has a variety of good units as well.
All the little war dancers don't match much but may be good for blade dancers if need be or maybe some Achillean Gladiatrix.
There are a variety of other Goritsi though not all are on sale or clearance so may be a bit pricey. Great miniatures though if you're a painter or don't care if minis aren't painted.
