ROM Hack What can be done with the QR.arc in Mii Makers romfs/models?

[Namesnipe]

So, I was digging through the Mii Maker files to find the stream [which to my surprise, was a .bcsar] but it was a .bcsar, so I began digging around out of boredom and found qr.arc in romfs/models, and I'm asking if it can be modified to allow the QR creation of special Miis as it controls QR creation. Is this possible, if so, how would I achieve this?
