Let me come right out and say this first: I want Skorne Construct Beasts.
Skorne has been in the west for a while now tangling with Circle, we've seen that it can be done, we have a head start on the techniques from working with AGs, we have a warlock who can transfer to AGs already, we even have some pretty solid incentive to explore the idea with the Titan Plague from the Forces of Skorne book and Rasheth standing to control the beast supply. It almost requires a bigger suspension of disbelief to buy that Zaal or Hexeris doesn't have someone working on this than buying the Transfer and Leaching mechanics in the first place.
If Gargantuans has Makeda3, Mammoth, and four Construct beasts (2 heavy, 2 light) with low DEF and FUR and high ARM, box count, and P+S for a Skorne beast and special rules that forbid Beast Handlers from effecting them (and maybe some shenenegany soul collecting goodness) I would jump up and down squeeling like a little girl.
What's on your wish list of things that make thematic sense?
