seriously, this is a digital camera not an good old mechanical film camera. By the time it got banged up like that from actual use I doubt it will be still functioning at all, so why not just go ahead and make it unique while it still works for you.
Just like some people swear by buying a brand new jeans and wear/tear it down through time, and some just get the pre-washed/teared one from store. To each of their own, if OP is happy with this, he owns every right to do so, not to mention it does take massive guts and skill to do so.
Grats on the handy work
