That'd save a lot of grinding time for when I need to go catch those Gen 5 Pokemon.
If you mean grind it on X then transfer it back to Gen 5, that may or may not work, originally there wasn't supposed to be any transferring back to Gen 5 from the Bank, but some say it was put in. If you can transfer back, it depends on if the bank changes OT or not, if it doesn't then things should be fine, if it does you'd still need the badges.
