Removing rear bumper chrome trim on C?

The more and more I look at the chrome strip that accents the top of the whole bumper on my C, they more I might think the car would look better without it there. I have a minor (but noticable enough to be replaced) ding in the bumper and the chrome strip anyways, so I'm going to have to get a new bumper/chrome trim which my dealer says is gonna cost me upwards of $800. I was wondering if I could perhaps replace the bumper with a base model bumper or something? I plan on adding rectangular exhaust tips which wouldnt look right with the exhaust cut outs on the C bumper anyways. Only problem I have is that i currently have rear back up sensors and would like to keep them.
Does anyone know if i can interchange a base model or touring bumper on my C then cut out holes for the back up sensors? Or any other ideas on how to achieve a chrome-less bumper?
