Recovery of an orphaned archive

This is a hypothetical

Scenario

     I have three years of archives (2007, 2008, 2009). I delete and purge the archive for 2007. 3 Month after I delete them I find out that I need some "important" emails restored from 2007. I go to do a restore and find that the SQL database files didn't get backed up properly and are corrupt. I only have the message center, Archive volumes and indexes.

Is there any way to get 2007 back into my current production SourceOne 6.6 installation?
