You know as well as me, that disturbing a sand bed will cause some nutrient issues that you will have to handle, along with the Alk, and Ca demands changing. Adding new rock will not impact the tank, but the amount of rock you are removing will reduce you bio load capacity until everything catches up. Might want to be cautious on feeding for a while, and measure parameters until things calm back down.
