Or get a bunch of Greg Rutkowski paintings and perform textual inversion to get an embedding of his style, which is what people are actually doing, and go back to square 1.
If the result of this is an image that infringes on his copyright — I'd imagine this would have to be a pretty 1-1 copy, since his style appears to very generic — then the burden should still be on the person who produced the image and published it.
