It’s a really interesting thought, and under ideal circumstances would work IMO. Obviously things are never ideal and there would be all sorts of roadblocks and gotchas as something like this was developed. Things we could think of now, and other things we probably couldn’t. Not to mention the whole problem of, “who develops it and how much trust can you give them?”

As I was reading the idea, it made me think of the suits from A Scanner Darkly that the undercover narcs wore. Basically heavily obfuscated the voice and displayed always-changing patchwork human features to anyone observing from the outside, including trying to hide body shape. Something like that could get similar results.
