Is there a way to use Go Launcher icons in Folder Organizer?

I really like Mitch S.'s Flat Icons . However, they are only available on Google Play packaged for Go Launcher . On Windows, you used to be able to extract any icon in .ico format from icon library or an .exe file and use it elsewhere. Is there an "app for that"™ on Android? I'm specifically interested in using with Folder Organizer.
