There is no guarantee they will restore your UMs due to the lag issues, as it is your responsibility for the up keep on your UMs with having reg runes or contis going.
If they do not restore your toons, then you can just pay up the $75 USD in AP cost to get a Character Revival, or see is someone is willing to purchase one for you in OPs, though that is a trade done at your own risk.
