There is TESDTK (The Elder Scrolls Dependency Tool Kit) that can be found in the http://www.tamriel-rebuilt.org/?p=modding_data/utils area. From the description on the site:
TESDTK
TESDTK is a tool that can remove master file dependencies from a plugin file. Everything from dependencies on other .esp files to Bloodmoon.esm or Tribunal.esm can be removed, which makes it a great tool for everyone who wants to take a look at plugins that requires masterfiles they don't have.
TESDTK requires the Java Runtime.
I used it a long time ago, I remember it working rather simplistically. Might be worth a try.
