Has anyone used the metal bars in the longer keys to tweak how they sit?

Example, my left shift key sits higher on it's left side then it's right. I'm wondering if I remove the key cover and bend the metal 'sway bar' under the key cover, if that will drop the side that is raised?

I've never done it. I'd be too scared. lol
