Those really are top notch, and yes, they really will serve very well for GoT.
Think these might well be the first Claymore Castings I've been tempted into...

That said (and I'm sure this has been asked a gabillion times before, but) any idea how Claymore scale in with Perry?
I can imagine the initial Claymore sculpts by Mr Hicks would be a pretty good fit. But knowing Matthew's sculpting work for Boot Hill, I wonder if these might be a bit on the chunky side to sit alongside the Perry WOTR/HYW ranges?
