Just caught up.. wow you proper fecked that wheel! it can be fixed although would need to be painted afterwards as previously said.
I never curb wheels, ever, however the one and only time I did it was when when I first got the Mazda, It was brand new, drove it for a couple of hours, picked up some friends and showed off some super quick parking skills I clearly didn't have for this car at the time!
Didn't know you had pepper pots on standby though, would they be a permanent replacement or temp?
