There's only so much customisation that you can get done with the configuration options alone, as you have surmised, however this is completely the wrong file to edit to achieve your goal.
The menus are created from templates kept in /usr/share/live/build/bootloaders. You are supposed to copy stuff from this into the bootloaders directory of your config and then modify it as necessary. Note that there are various placeholders within the template files that get filled in during the build process. So, copy the template directories for any applicable bootloaders into your config bootloader directory, determine which files you wish to customise and then customise them. You can remove from your config any that you're not modifying.
