I think I've heard of something related, however some pictures might end up being way less transformative. If for example, one took an image of Micky Mouse and another one with glasses and all it did was add glasses on it with the majority of the picture obviously looking like it just merged two Copyrighted images together, then we might have an issue involving Copyright.
Though less related to your comment and more of an added take to my original comment here:
There is also a risk of being less transformative with traditional art too.
