Slight chin asymmetry and implant: would an implant make things worse?

My chin is already slightly asymmetrical. It is invisible to the front view and you can only tell if you see it from an absurd angle. When I run my finger across the chin bone there is a small bump of bone going forward. If I were to get a chin implant, would the implant exaggerate this slight asymmetry, or could the implant be carved slightly to accommodate this bump.
