Looking at the metacity source I don't think it currently has the ability to pull this from theme rather than gconf, but it doesn't
look that hard.
meta_frames_paint_to_drawable calls meta_prefs_get_button_layout
but it doesn't look that hard to add another string to the theme definition and I guess you would then substitute
that call in meta_frames_paint_to_drawable
The problem is all the ancillary work in the changing the theme chooser/overrides.
An interesting question is when should something be part of a theme and when should it be a pref.
