You could abuse the embedded bootloader config and add a small amount of data as (for example) a commented out base64 blob. I use that to store some per-device info for my http booting OS and have that accessible in 'vcgencmd bootloader_config‘. I don’t really understand the rest of your question: if you want things secure, just use the provided secure boot mechanism. I don’t see how your suggestion would help or work?
