I feel like it would be easier to just increase the bust slider beyond 100% rather than placing shoulder pads into the chestpieces. This would result in unnatural shapes in many cases, depends on the chestpiece in question. Also, some chestpieces this doesn't seem like it would be "logically" possible. For example the Light Steel Galerus. The chestpiece is clearly a solid metal piece, so how would you hide the pauldrons/shoulder pads in the chestpiece? There's no where for them to fit!
