Putting my own kneejerk distaste for AI art in erotic games aside, I think part of the charm of California Strip Poker is the strong sense of space and layout, the continuity between shots. You're not just unlocking a series of pictures of an increasingly undressed woman; you're seeing Denise on the couch, her clothes discarded next to her one-by-one, her pose shifting as more of her's exposed. She doesn't look half bad in the AI art but the backgrounds look like they exist in a big void and that cuts out a lot of the appeal. And I'm no expert here but I don't think you can train the AI well enough to keep a sense of space in its head; the background is always going to be shifting a little.
If you want to use the AI art anywhere, I'd suggest making some kind of bonus gallery with one-off pictures rather than making a whole strippable character out of them. If you win with Maid Denise four times, you'd get to unlock some AI images of her in the same outfit, perhaps.
