I had the exact same damage on my MBP. I took it apart and bent it back in. It is really simple. Just have to get the stuff behind it out of the way. Also, you can totally replace the bottom case of it too. Sometimes can find those for a few hundred on eBay. Do it yourself and change a ton.
Funny thing with mine was, after I bent it back in, the plastic separated on the front of the casing and Apple replaced the whole bottom under AppleCare. There is hope.
Good luck.
