I don't think generic AIs are the right approach anyway, I think we're better off with precise procedural models with a lot of knobs and some knowledge of rules (eg. metahumans).
Maybe you can put an AI in front of it to generate what you want using the procedural models, but pixel output is just not good enough for games.

I've been using https://github.com/xinntao/Real-ESRGAN to increase AI renders resolution, it works very very well on some styles, you can easily x4 or x8 the resolution if you know what you're doing and have some photoshop knowledge for the cleanup
