Hmh yeah, it does sound like it was more RTD and the production side of it that got all excited about the Cyberwoman design, rather than it being scripted that way. To be honest I was never particularly offended by it though, although obviously it gets pretty silly when you think about why logically a partly-done Cyberman conversion would turn out that way. But then I was completely out of step with popular opinion when it came to that episode anyway! I found the confrontations between Jack /Ianto and Ianto/Lisa pretty powerful, yet there seemed to be very widespread mocking of Gareth's acting being really O/T afterwards, and everything about the episode being just awful.
