I have an idea how to protect my seed phrases.
Wasnt the BIP39 passphrase invented for this very reason? Look, multiple layers of encryption sound good in theory, but you are just adding complexity and failure points. If you forget a password, mess up the encryption, or lose a USB stick, you are screwed. BIP39 phrases are strong enough on their own if you write them down on paper, split them up securely, and keep them safe. This feels like overthinking it and inviting trouble.
Besides, I cant think of a single advantage why it would be better to store a seed phrase on an electronic device like a USB stick rather than written on a physical medium like paper or a steel plate.
