The "spares" you have amassed I would say, in a strange way, are a "benefit" of running a GP bike! Like you say, buying consumables in the quantity required to maintain the bike is going to leave you with a wide range of, technically left-overs! The more left-overs acquired, the more use they become when you start to mix'n'match as you do.
The funny thing is, probably 75% of internal parts (beyond HRC RS service life) you remove from your motor would be fine to use in an NSR.
