Well, Azog is rigged to the "Deathbringer" SKL, and it's actually a little more different that I first thought. It has some attack anims that Lurtz don't. Same with the Sharuu SKL that they will use for warg. It's a bit different from the regular isengard warg rider SKL =)
And also, the proportions of the Rogash body would not fit Bolg, so the bones would be outside the body
