What would be really interesting, and possibly impossible to do, would be to get all the character designs that were rejected during the development process at the various studios. As has been pointed out in other comments, the GAN is generating some pretty boring variations of faces from source material that has been focus grouped and designed by committee to death before being released to the public. I have seen some really cool and wacky designs in the hallways of DreamWorks, Blue Sky, Pixar, etc. during my time in the industry. I would love to get all of those designs into a training set as well.
