Sure, more than possible. However keep in mind again to get game quality CGs this would take months of image generation and editing. Also having a team of people working on it would mostly likely end up looking messy and inconsistent.
I am just more on the line of let's hope Starmaker is picked again for the next project and it is built from the ground up with these features in mind.
Yes, I agree with your idea. The gameplay and replayability of this game are excellent, and if the development team increases their investment in it, it would be a win-win situation that we would both be happy to see.
The mod concept is actually quite simple; the developers only need to provide a port to serve as a foundation for players to add their own content. If they are worried about any "unexpected" issues, they can simply provide story mods and image mods.
Regarding game-level CG images, I don't think this is a troublesome issue. It's clear that the game's CG images are AI-generated pixel art, which requires AI quality rather than artist quality. And in my opinion, the quality of the images you've provided so far is already sufficient for the game's needs.
As within game, my images go through about half an hour of Photoshop clean up and editing after a successful generation. That is not accounting for in game they are obviously scaled down and filtered to obtain the pixel style which most likely results in even more clean up and optimisation. Yes this game uses AI assets, but a lot of manual work goes into cleaning everything up. It is not simply spamming a Gen button...
