I voted yes, but not because its too small, it seems about right for the game. But with it working as and Item/Magic meter then i dont see why all the old upgrades couldnt be there, like the one where all of the meter use is cut in half (i.e. ALttP), one to make it longer though after the last example its kind of over kill, but i still always liked having both!
And depending on what all uses the meter, say like if using your spin attack, and rolling and dashing and what not, if stuff like that uses the meter i would like an upgrade that will make it to where actual Physical attributes and actions dont use the meter, making it then strictly for Items and Magic, NOT stamina!
