Kudos for Not Cutting on It!
Like most respondents here, I am a stock purist. I resist the urge to irreversibly customize all my toys especially guns, motorcycles and cars. Having said that, I give you credit for not cutting, milling, or drilling on this classic masterpiece. Every one cut up is one lost to history that cannot be retrieved. The grips may not be every one's favorite, but only one brass scew stands in the way of authentic restoration. Cerakoting is a bit more intrusive, but the beautiful mechanical work sits underneath, intact and preserved for current and future admirers. FWIW, I like your color selection better than nickel plating.
