I was having the same thought recently! If I can figure out how to make that so, I might add it! I think it would be good to make a poll for that, to see how many people would like to see that change.
also you might have found this too but just in case if this helps :P (for the changing enemy sprites)

On the same link one of the comments had a super interesting idea, to somewhat animate the front view battlers by changing their image. Basically if the enemy attacks, it changes to a attacking stance, and returns back to normal after the attack is executed, posted by quackenbirdt, and the poster made a plugin for that too if you'd be interested!
