That could certainly work, though as the Ankheg Breastplate's regular benefit is an Armor bonus to AC, you wouldn't be able to get its full benefits and wear armor at the same time.  The Kruthik Claws might be a better option there, since you'd get two claw attacks as well as bonus acid damage, and a nice boost to Hide and Move Silently.<br/><br/>You could add on the Wormtail Belt to increase your Natural Armor bonus, and then find something with a good Crown, Feet, or Hands bind, and then after that, you'd have two spots left for whatever you wanted...
