I dont think you should change the region of your shop channel and I will explane why. Lets say the console is a NTSC U console. If you were to change the shop channel to PAL, then you would have to watch out for future updates. A disc update could brick you if a problem occurs when updating that channel since it would currently be out of region with the rest of the system. If you really want to change the region, do it for the entire system.
