Absolutely. Waifu Labs https://waifulabs.com/ implements a grid-based choice system for evolving anime portraits, and Artbreeder https://artbreeder.com/ implements controls plus crossbreeding and other features for a variety of StyleGAN/BigGAN models. There's plenty of scripts and Colab notebooks as well for various kinds of editing or control if Artbreeder doesn't do it for you. (I think Runway may also do editing but I haven't used them in ages.)
GAN models do not need to be specifically architected to enable control, because you can reverse them to get the latents/seed and manipulate that to 'edit' images: https://www.gwern.net/Faces#reversing-stylegan-to-control-mo... So if someone wanted, they could use Arfa's model to edit images.
This is incredible, thanks for sharing!
