Last I heard, Firebird is not slated to permit cross-database joins.
I handle this problem with a small suite of home grown java tools. I
can't give you the suite, but I can give you some ideas. The core of
the suite took me less than three days to write, so you can see it's not
a hard problem.
To java, any DBMS is equally accessible. Set up a configuration file
(or table) that indicates what tables and columns tie together, run your
queries, and let the tool do a nested loop join.
Since my tool is also a data pump and transformer using XML technologies
at its core, generating a report is a matter of applying an XSLT
transformation before pushing output to a file stream.
I hope this helps
