Most of the units should be fine as the base sizes in dust warfare are 30mm and Im pretty sure alot of the supernatural units have the same vibe as in SOTR. The apes can be replaced by SOTR werewolves, The zombies can be replaced with sturmzombies so most of your models can be fine, the only other things you need are packed lmg models, Sniper models and models with assault rifles. As long as your models are around the same size and on the same sized bases it should be fine, minimal conversion needed.
