Hello! Deakor, you may want to check certain tool 'Seamless 2' on Creative Market (I'm afraid it is not allowed to post here link to other marketplaces). Various methods for automating seamless textures are covered as part of features description, please take a look for inspiration. If you would rather see detailed description done by one of (potential:)) users, let me know.
BTW, it is nice to see animation environment like PixelOver growing. I was waiting for a long time for something covering ground between After Effects & Aseprite.
Have a good day!
