I'll be honest with you: I have no time right now - too many commitments I'm already have trouble to keep up with.
That being said, give it a try! 16x16 pixel art is easy animate and it's fun. You can also just rock and/or squeeze the characters/weapons programatically and get nice results like this one: https://loner-dev.itch.io/almas
Sorry, I'm not able to be more of a help but I wish you good luck with your project anyway :)
