Sadly it is not possible, their are ways to put GSC scripting into a CFG but a-lot of it(especially HUD and Text Functions) depend on GSC files from the patch. CFG also does not have a-lot of functions on it like a gsc file does(include, if/for statements, etc.. ). The closest thing to scripting as from what I've seen are menus with iPrintInBold and iPrintIn which are universal and work at anytime, more of a command kinda thing.
