Would it be possible to add a option to invert the auto-shot bar so that it fills when you can cast and empties when auto-shot is casting.

I decided to look into this myself, and after some tinkering i added a checkbox to invert the hunterbar. While i was at it i also added a checkbox to disable the green flash after using multishot. I have attached the file just in case you or anyone else might want it.
