So, this is pretty much backwards from how police sketches actually work and it would likely obliterate any reliability from the system (which, as I understand, is very low already - and even worse for computer-generated imagery).

People have bad memories and bad perception in stressful situations. They don't actually know what the person looked like; they don't have a strong model in their brains. Police sketchers use clever questioning techniques to get details about features that people wouldn't otherwise think to describe or even realize they have knowledge about. The truth is that there is an absolute limitation to the effectiveness of any facial image reconstruction, which is the limits of human memory. Adding AI to the mix can't change that, but it's extremely likely to influence the witness to describing a less accurate face with higher confidence. In other words, a disaster.
