Me and my friend both had the idea of a mod that added a 'sort of' hidden inventory toolbar slot, that nothing can fit into and can be accessed by pressing '0' on a keyboard and when it is used your character holds nothing so you just see their arm as if you were holding nothing. A Slot 0 if you will. The key that is used to access Slot 0 can be changed in the options from 0 to say `/~ or anything that the user wants. Visually on the toolbar it will look like there is no selector ring a quick Photoshop of this would look like this below.
Default:
Slot 0 selected: (Note: Green background is Green Screen from Extra Utilities)
I've included a poll for you to show your interest in this mod, If enough people express interest, I'll start coding it and when it is done i'll release it for public use! (under a Creative Commons licence of course.)
Slot 0 selected:

If I were a coder I'd work on it.
-but u cant use the slot and the slot should be after 9 btw
or the slot would just be invisible
I can try to write this. It should be fairly simple as long as you don't want that extra slot to be able to hold anything.
