so I know you can unlink a NNID using God Mode 9, and I was wondering if I can unlink the source 3ds original NNID, create a new one just to get the dsiware needed to use sudokuhax on, make the system transfer, finish the set up on target 3ds, unlink the NNID on target 3ds, restore sysnand on source 3ds, and finally relink the previous NNID's corresponding to each system
