Zimph, you've been pretty vocal recently about your love of stripeless Aqua and how every themer in the world should release raw Extras.rsrc files for you. Since you are comfortable swapping resource files in /System, and more importantly, you aren't using a theme that requires anything other than a raw Extras.rsrc file (a statement which does not apply to many themes nowadays), why don't you just ask someone you know who has ShapeShifter to send you the generated Extras.rsrc file that ShapeShifter caches rather than try to impose a burden on themers who already work harder than they should just making the theme?

Easier for everyone.
