Brother I hear you, I do. The problem isn’t the workplace, the problem is that some people will find this unprofessional enough to bitch. Any public facing anything for any company will be heavily scrutinized by a subset of people who actively look for things to bitch about.

The professional, whitewashed and soulless veneer on every professional website is the direct result of hoards of bored idiots with nothing better to do than bitch about any perceived insult, however slight. You either have an organization that absolutely revels in it, or you end up with the same safe corporate bullshit everyone else has.

With a press brake it would take a few minutes. Doing something at home with sheet metal that thick is going to be a bear of a job even with a sheet bender. You might be able to find an outfit online willing to do it for you, or at the very least cut the sheets for the fab shop to bed for you first.
