The brighter sound you think you may be hearing is not necessarly an improvement

The "ideal" tone of guitar is 100% subjective, so everyone has their own idea about what that sounds like. Even the luthier who created your guitar might have had a different idea of the "ideal" tone. What sounds perfect to you might even be regarded as a failure by him - if he was aiming for a fingerpicking guitar tone and came up with a flatpicking tone instead, for example.

Bridge pins won't make a huge difference, but like strings they can fine-tune the characteristics of what you already have.

Ask yourself... is this really the direction I want to go in, especially with a higher-end guitar?

Well since it's 100% reversable, the answer is going to be "hell yes". Why would you think it wasn't?
