I have this idea for a 2/3 mutlisig setup that, to me, seems like the right mix of convenience and security. But I'd like strangers on the internet to roast and poke holes in said idea

• Seed#1 is to live in a hot-wallet on my phone and be backed up by a password manager.

• Seed#2 is being held by a hardware-wallet and be backed up by my memory alone.

• Seed#3 is not actively used and is written down on metal inside a physical safe in my home.

Of course the xpub needs to be backed up as well.\ I like this idea because I'm in direct control and have access to all seeds at all times. But each seed lives in a different realm of existence. One in cyberspace, one in biospace, and one in physical space.
