No I dont want these specifically, but if they were an army builder in addition to the Horde Troopers, able with extra heads and such, that'd be cool. And yes, I would want their bodies to be the same buck system, no unique sculpts for these guys.
And more to the point on this topic, no I dont think in any case they should be a 3 pack. 2 pack with alot of parts. Not these characters specifically, but generic soldiers who could be creating any of them, similar to how Black Guardsman isnt Clamp Champ specifically (though he totally is for me, hehehe)
