No, you either need to connect to the Nintendo Servers to transfer your account, or you'd have to decrypt and transfer manually which could only be done to another CFW system which is pointless, and it'd make the recipient system more obviously flagged than the donor.
If you just want to preserve Pokemon, the best bet is to get PKSM, transfer your Pokemon from Bank to PKSM, then use either a game card or local wireless to transfer to a clean Pokebank system when necessary eg to transfer to next gen.
