I’ve been thinking about this since i finished dialtown, if Mingus was able to get surgery and model her head after a real cat (due to having an image), would someone be able to have surgically reverse it (if having a photo) and have something that at least mimics a flesh head??
This is a question I've given a lot of thought to.
The short answer is: not really. One reason is: It wouldn't be feasible with the level of technology present in-universe. Mayor Mingus' head cost a LOT of money, almost bankrupting the whole city, and the process was not easy or seamless. In the same way men haven't landed on the moon in decades, it's not literally impossible to do another animal head again, human head would present difficulties.
The end result of an engineered human head would have... issues. It's hard to create a truly uncanny cat face accidentally, we have AI generators that produce very convincing fake cats based on images of normal ol' cats. But, human faces are viewed by the human brain very differently. Our perception towards minor differences in face shapes, how faces bend, how we read eyes, our brains are comparatively superhuman at detecting issues in human faces.
Hell, even with cutting edge CG, human faces are hard to digitally replicate from scratch without creating something majorly uncanny. It wouldn't be impossible to try, but the result would be likely horrendous and would defeat the purpose of whatever it is that you're trying to do, except perhaps scare people? Cats are scared shitless of Mayor Mingus in-universe due to this same effect. Deep within their DNA, they know from her physical appearance that she is deceiving people in a malicious way, just from looking at her!
Oh. There's also another reason, partially related to the last one, but I'd have to explain more about the Dialup to answer it, which is something I'm avoiding explaining due to something that's very difficult to explain quickly. I'm not being frustratingly enigmatic as a troll, trust me, you'd understood if you knew. Another time, perhaps.
