The idea reminds me of this. From memory Peter suggests setting up a multisig with 2 android phones.
My issue would be the firmware. If you leave it in your drawer for 5 years is it going to turn on or push updates before using it? I like how it would be hidden in plain sight though.

That’s why you’d have the private keys and the multisig descriptor backed up in case the device doesn’t power up anymore.
Phones could work as part of a quick and dirty multisig to reduce access to funds, but I wouldn’t necessarily use them as singlesig hardware wallets cause they’re not designed for that. Of course depends on how much you’re securing.
