Good news and bad news. Good news is, yes, your billets can be replaced. Bad news is, you shouldn't do it yourself, and in most cases won't be able to. You will need to send it to a saddlery to have them replaced.
If it's only cosmetic, I wouldn't worry too much as when you are riding, they won't be seen. If the leather, however, is what is in really bad condition, I would replace them.
Be careful with trying to soap and clean them too much, as this will only make it worse. I actually cheat and put a leather dye on mine that our local saddle shop suggested to make mine look better.
