Changing SQL statements inside the database

Hello list

This time I need your help on how to implement a weird idea. We have a third party application that fire wasteful SQL's to the database.
(Remember the discussion on using x$dual Vs dual some days ago?)

I am wondering: Is there a way to change the SQL that the user send?

In ADABAS on the mainframe I can activate a user exit that gets the command that
the user send to the database and change it (Not only can, but we are doing it!).

Is there a way to do the same with SQL in Oracle?

In the server (preferably) or in the client.

Thanks
