Okay, so I got the Ultimate Iron man upper torso and attached Cable's muscular right arm. It looks a little bulky, but nothing too comical. I tried to put Jean Grey's arm on the left (modern Cable doesn't have the cybernetic looking arm but instead has a very emaciated looking arm with a prosthetic arm over it. The problem is the female arm looks absolutely ridiculous on the iron man torso...just way too tiny.
So I'm wondering if anyone has a suggestion for a replacement? Again, it's a scrawny bare arm. I'm going to scratch build the prosthetic arm over it.
