This is not exactly what you want, but it could be close:

http://www.telesiscomputing.com.au/dbk.htm

The backup process performed by DBak duplicates all tables
into a new database with no constraints defined. Thus you
can edit any of the data in any of the tables in the backup
database using something like IB_SQL or whatever.

Both console and GUI (Windows only at this time) versions
are available.
