Storage Solution - find my weak points

Tell me my weak points:

Trezor setup and all BTC successfully confirmed on it.

Trezor stored inside two fireproof bags in massive 120 minute fire rated home safe bolted to ground.

.008 BTC on the “standard” non-pass phrase wallet.

Duress code activated.

PIN code + passphase protected.

Multi - share wallet (2 of 3) created. All stamped titanium plates with security stickers. Passphrase broken into three equal lengths and each third etched on one plate.

Titanium plates stored inside zip locks inside a fireproof bag. All three are geographically distributed - each in a different banking institution’s safe deposit box. Three different states each no real overlap of natural disasters that could affect them.

Instructions given in our will to break them open. All boxes held in a Living Trust.

What could go wrong? Break this for me so I can improve if necessary!

Thanks!!!
