There is one thing you might be able to try: There has to be a copy of the /boot directory someplace on that (failed) disk with the keys in an unencrypted form, otherwise it would have been unable to boot at all. Depending on how the disk failed, there's a chance that (relatively small) section of the disk survived, and could be recoverable by a disk-recovery service. But that's my only thought to a hope...
