I don't see why you couldn't tone the power down a bit and thus get full use of all the units you want. Perhaps this is a Malazan expedition outpost sent from their homeworld? Thus they would have to rely on the skill of the "natives" and be slightly worse than they are on their home turf. Perhaps the local setting works against them as well? There are a bunch of godlings walking about in the neighbouring empires after all. Perhaps something very dramatic happened which explains the presence of the pretender god in their empire?
