Is it possible to reset sealed deck slots?

Because the card pool that's tied to a particular slot somehow incorporates the account name in the seed for the randomization function the game uses for creating your sealed pool, if you're playing on a platform that allows you to change your username, it may be possible to delete the sealed deck data on your platform, change your username, and open new boosters in that slot.

Alright, I have it on PS3, the only way I've found to make a new sealed deck for free is to go into the save data utility in the game tab and delete the "magic" save file. Downside, this will also delete your campaign and player stats, but it will open up the chance for more sealed draws for free.
