Button to rotate weapon 180 degrees in the hand?

[plucky adder]

Would it be possible to add a button press that made Willy rotate the weapon so the backside of the weapon faces towards the enemy?

I feel like there are enough weapons where the option to use the "backside" of the weapon seems viable enough to warrant the option, if possible.. (and i will admit that the thought of beating the brains out of someone using the blunt side of the woodcutting axe does feel vaguely amusing too)

It's a good idea
I'm not sure about additional buttons, controls take half of the screen as is
Poleaxes are quite good in short grip, there you can hit with either on sides easily
