More Player Animation

As the default player animations are kind of stiff, especially compared to the trailers for the game I would like to see more options for player animations, maybe in an animation pack, where you can change the way that you walk, run, swim, and things like that. 
For Java it could be a thing in the settings and for Bedrock you could get more animations on the marketplace or something like that. 
It would also be nice to have climbing, and free falling animations.
