The way to do this would be to boot from the external drive, and then use SuperDuper! to copy from the boot drive (the external) to the internal drive.

Shouldn't be a problem. But, let me suggest that you shut down after, and detach the external drive. That'll force aliases to resolve to the internal (since the external won't be available).

Hope that helps!
