I suppose in your case it'd be possible to refinish the cones but I'm not sure what could be done about the cups other than custom making some races to press in there... and that's not much of an option. If you definitely want to ride them, I'd personally just throw 'em back together and ride 'till they blow up. They may not be the smoothest but I'd bet they'll last a good long while before they give up completely.
