My apologies: I missed the bit about Disk Utility. You can't do it with Disk Utility if there's Time Machine data on the drive and you don't have enough space to hold the whole thing.
But why would you? As you said, you're able to start up from the backup drive. As such, you would do so, then restore with SuperDuper! using the "Restore" copy script.
