Yeah, you could do some horrifying things nowadays with cgi - bottom jaws replaced with mechanical parts, multiple mechanical appendages added to the body, holes in the middle of the body because the Borg deemed them irrelevant for that particular drone.
I always liked that scene in Best of Both Worlds where Locutus is being upgraded and there's a tear running down his cheek. Maybe that could be a constant for the drones, showing how horrified they are at there bodies being mutilated and having no control over their actions. Why the Borg would allow that, I don't know. Perhaps it's a malfunction they haven't quite worked out how to solve.
