My motto: If it's structurally stable & you like the tone, leave it alone! There are a slew of generalizations about best practices in guitar construction, but the wood in your instrument does not know or care about those generalization. Imho, they represent positive reference points to look for when assessing an instrument, but that's it, and each piece must then be assessed on it's own merit. If those generalizations completely drove our actions, there wouldn't be a single 1970s Guild left on the planet with a rosewood bridgeplate!
When you start to tinker with a key component like the bridgeplate, you will most likely alter the sound to some extent. Then the unknown raises it's head: Has the resulting change moved in a direction that you find more pleasing, or less pleasing - compared to what the guitar is doing for you now?
If you're unhappy with some aspect of the tone or have structural issues that must be corrected, by all means, tinker to your heart's content & maybe you'll realize a degree of improvement. But if you love it the way it sounds right now, consider that the original bridgeplate has been on there for 35 years, and is probably a very happy camper. If significantly modified, a portion of that lovely tone may disappear down an altered rabbit hole. I once had it happen with a sound I truly cherished, and it took me approximately forty years to once again come across the same model with that exact tone. Glad I lived long enough to hear & own version 2.0. It puts a smile on my face every time!
