No, it's got to be "as issued". You can replace parts, but they've got to be either of contemporary manufacture or substantially the same. If it's in, say, one of those Tapco stocks, it's not C&R anymore.
As far as "disposing" of it in the bound book if it's been altered to not be C&R anymore, I don't see the harm in that. It may be a belt and suspenders approach to the rules, but in this day and age, it's probably not a bad idea.
