I'm thinking if you got a new hive with foundation, cut one comb of brood out of the existing box, and tie it into one of your new frames. Then place the new box right on top of the old one, without the bottom board, just like supering. Bees should move up to tend the brood comb, and go to work on the foundation if there is any nectar coming in. Check in a few days to see if the queen moved up. Once she does, move in a queen excluder. Once the brood has emerged, cart the old hive away, put on your bottom board, and it's off to the races
