I don't see why not if it goes through the authentication. I also don't see why you'd want to - downloadable meh-ni-games (see what I did there?) are meh anyways.
I want to be able to transfer my Ambassador titles, Animal Crossing: New Leaf, and Pokemon X games to my 3DS XL's smexy XL screen. I have a normal 3DS on 6.3 and a XL on 4.5. So being able to system transfer would be awesome. (Let alone restoring NAND dumps. I could transfer games back to the normal 3DS and restore the XL's SD NAND back to when it still had the games.)
