Other than the periodic squigeyface, this is pretty close to perfect. We are 95% of the way to seeing minutes-long fan animations that are close to indistinguishable to the canon ones. Of course, the last 5% is always the hardest.
Of course, Hasbro lawyers tend to strain at their chains when fan works get close enough to potentially cause confusion (see JanAnimations). Maybe the fandom should produce some designs (and LoRas?) that have some de-serial-numbered characters.
