No.  The journal file only records updates to the zone.  At best you would 
only recover the changes since last commit to the zone file.

It doesn't sync the files to make two equal copies. It applies all of the 
outstanding transactions in the journal file to the zone file and then 
empties the journal.

Yep, the journal is out of sync because the zone file is non-existent.

Oops.  That's what backups are for.  Slaves are not backups.  However, you 
might be able to extract some meaningful data from the slave's zone file. 
It won't be pretty though.
