Change keybinding to show Unity Sidebar

So I really, really don't want to have to un-learn all of my "Win/Super" key bindings. And it occurred to me: there is one key on the keyboard that I never use: Caps Lock. Can I make Caps Lock do what Super does by default?

Note: I do not want to simply map Caps Lock to Super, because that would defeat the purpose of giving them two separate functions.
