1. clone your player object (rightClick clone and click on the viewport)
2. rename it "playerSkin"
3. edit your player object, delete all animations, delete all the frame of the default animation, and just put a rectangle on frame 0.
This way you won't have to rewrite most of the code
4. on event sheet do an "always -> playerSkin set position to player"
5. just for the part concerning the animation on your event sheet, rewire that on the playerSkin object
And be carefull about origin, put everything on the bottom it's easier
