Have the option to use Java editions animations and interface on bedrock

Have the option to use Java editions animations and interface on bedrock. I don’t like bedrocks hand while in first person, But I think Java nailed it! So this would add the option to switch to Javas hand, while also adding the option to use the combat cooldown that is on Java, on bedrock (as a second option so you can use them separately without needing the other one on) And the player animations you would also have a option for.
