Inter frame expression image generator

Hi,
I have an idea for a ai agent or some such, and wanted to run it by people,
a plugin for a drawing program like gimp open source preferable, where it allows users to generate images based of a previous image of the user only, and then generate a new frame focusing on the expression of the facial features but tool the image generation so that what comes out are suggestions or a cycle of generations around some key visuals with maybe a couple of sliders for factors related to key facial feature types, sorta like how they have the face editors for video games but in stead of a hard slider its a range within the slider cause ai is a generative thing, and you set emotional temperatures what you want, like i have this somewhat expressive character, make it seem more anxious, the ai generates say 1 to 5 images based on user preference of load time vs content generation. and then from there its a stencil NOT a copyable image so that ai generation isnt directly interfering with its own data set.
