This mod exists in modern versions, it basically lets you change the size of your items and their position, this will probably be complicated to code for 1.8.9 but it will be really cool
This will also allow people to use block hit overlays without the swords looking so weird and out of screen (as far as I know)
Here's a video on the mod: https://youtu.be/qQQERTcMXzs
