the only way you will ever get anything like that is if you try build yourself a custom .3ds file and extract the dlc and attempt to merge it, but imho that is the biggest waste of time feature gateway could add, SD cards are dirt cheap, you already get one with the 3DS and if you lost it or whatever you wouldnt be able to use gateway in the first place, so again its a pointless feature request as good as me saying I need them to make the gateway card fit in the SD slot as my card slot is broken......that isnt their problem
