If I got the Chaos terminator lord/sorcerer kit, what bits would I need two of in order to make both models?

I have been using blue stuff and milliput to make extra Ork legs and torsos, Krieg Killteam bodies, and replacement parts for broken spindle drone legs from Blackstone fortress, so I’d like to save some money and make both the Lord and Sorcerer by cloning a couple bits.

From looking at the sprue, I think I’d need to copy the legs, pelvis, and back of the torso. from those with experience with this kit, is there any other bits I’d need two of?

I would skip putting a cape on both of them, and could come up with alternative basing instead of the tactical rock.
