I want a version of this for manga (for translation). Right now I think the go-to lightweight inpainting model for anime and manga is LaMa which is several years old now and it feels like there is room for improvement.

I've been working on trying to outpaint an animated program for my son (Leapfrog Letter Factory if you're curious) and then upscale it. Doing so locally has been actually fairly difficult. I wonder if you could retrain or fine tune this model. They mention building an expert, I wonder if that expert could understand more about translating various characters.
