Hardware wallet vendor redundancy

Before I dive in, please do not try to replicate this setup if you are not confident with what you're doing. You're more likely to lose your bitcoin yourself than to a hack.

I do believe that a good single sig setup generated with dice rolls and a passphrase is more than fine but after the recent news I personally am not comfortable relying on a single hardware/software vendor ( I use a seedsigner I built myself but I would still like the security of another different hardware wallet along side)

The essence of this post is 2 of 2 with passphrase VS 2 of 3 for my circumstances, everyone is different though I believe a lot are in a similar position and this post will be helpful. I am not saying to use my method, I am posting it to have feedback on potential flaws in my plan.

My circumstances are, access to a single safe property. I don't want to rely on a single hardware wallet vendor. I do not want to use any 3rd party companies.

(I am going to change my setup slightly from what I post for obvious reasons)

The plan:

- Acquire two different bitcoin only hardware wallets

- generate a seedphrase using the dice roll method, find the 12th word using a hardware wallet (Seedphrase A with device A, Seedphrase B with device B)

- add a secure passphrase to one or both wallets (The password needs to be long enough to avoid being brute forced ~20 characters including numbers, symbols and upper and lower case letters)

- Boot Tails OS from a usb on a device with no internet and use Sparrow to create the 2 of 2 multi sig wallet, (no need to backup the descriptors if the derivation path and account numbers are default, but worth doing anyway. The accounts also have to be in the right order but there is only 2 ways to try) and add the public key to the Bluewallet app

- Stamp each seedphrase into two metal sheets. Seed A and Seed B will be stored together in two different locations in my property

- The password will be stored on my phone/pc and sent to trusted people. I don't believe the security of the password needs to be high on my phone and pc, the only job the password is doing is protecting my bitcoin if either of my seedphrase locations are found.

I believe a user is less likely to lose access to the 2 of 2 with passphrase wallet than a 2 of 3+ wallet due to the extra information not being needed (Descriptor etc) if access to one of the seedphrase backups is lost. This method also means that only two safe separate physical locations are needed rather than three.

Is there anything i'm missing or potential issues with this?
