Having worked with Warres for a while I would suggest catching the queen as well. Put her in a cage with a sugar plug and move her into the Warre box. Graft a frame or two into the warre box and let the bees move into the Warre. It might be difficult to graft like was said but I think your chances of success are far greater this way then trying to the get bees to move of their own accord.
I've now built well over 30 Warres for different people and the best thing to to populate with a package or swarm. That give the highest chance for success. I know that doesn't allow for local bees but I would rather have them stay and build a stong hive then fail to move and possibly swarm. Another thought would be to purchase a local queen and then swith the queen in the package for the local queen. You would need to let the package get used to her scent for three days or so before hiving but that way you would get local brood as the queen would have mated locally or will mate locally and the 10,000 or so worker would slowly die off and be replaced by the brood of the local queen. You might get the best of both worlds that way.
The only draw back to that would be the stress to the bees and how long they have been in their package. I have had success in keeping a package for 3 days or so due to weather not permitting a hiving. Just make sure you spray with water a few times a day to keep them hydrated. There should be plenty of sugar water in the can that they are shipped with.
