The MCP Skunkworks has some files http://www.tesnexus.com/downloads/file.php?id=26348 which you'd need to edit GMSTs through scripting. The current builds of MGE XE include special MWSE functions to read and write GMST values, and the "GMST Reference" link should show example usage.
You'll need MWEdit to compile MWSE scripts, as usual. Good luck!
