Form follows function...
So far I've added BMW panniers because I needed the functionality of these cases to haul my stuff (MC gear, RC gear, Student gear, etc.) and a set of TT bar risers to relieve arm/back pain. Can relate to OP's thought process though. That said, had I more financial bandwidth, I would join the ranks of Farkle-holics Anonymous in a heartbeat! Cheers!!
"So, where did I hide my keys... This time?
