This sounds like you used ChatGPT 😂 I would stick with bitcoin only and not advise people to walk down the path you’re suggesting. Every hardware wallet/signer/electrum/sparrow can work with bip39 native Bitcoin backups. I would always advise a Bitcoin only setup for the hodling of bitcoin. It’s multi generational so I would go for a more “standard” approach. Single sig with passphrase or a multisig is easy these days.
Have you ever tried a passport or a seedsigner? I would advise you to try it.
