Is it at all possible with the Moguri framework to "add-on" more generated art, as to 'extend' the widescreen effect in scenes where it isn't present?

I'm not sure if I'm putting this across right, but I made a (quick, low-quality) example to illustrate my point.

Again, this is just something I whipped up quick in photoshop. There are systems which do in-painting excellently using a combination of GAN and ML.

If indeed someone were to generate art for the missing areas, would it be possible to add this to Moguri (or some other mod) somehow?
