I don’t know if this is possible, but here’s the custody solution I want:

2 of 3 multi-sig where I hold 2 keys and the custody provider holds one. Their one should then be multi-party requiring at least two companies to verify me before signing. All three on different audited hardware.

I want an empty security address pre-established that is a 3 of 5 with additional wallet types used. I want a duress key that I can activate with minimal friction that will sweep everything from my 2 of 3 into my 3 of 5. In that case I want the custody provider to still require multi-party, and one of them should verify me (or my heirs) in person. The 3 of 5 should also be time-locked so that it takes a predetermined amount of time (2-4 weeks?) to move funds. That would allow some geographic diversification of keys, without creating a time-based crisis).

Custody provider also has a hot wallet on the same platform that allows me to pull from cold storage to my own spending wallet in limited amounts and with time delays. Hot wallet has ACH/wire/bill pay.

Custody provider also offers 1:1 insurance of cold storage funds. Additionally they offer lending (including mortgage) on platform.

Additional services: Buy/sell on platform. End of year tax forms. IRA’s. Trust accounts and built in inheritance.
In person support for set up and trainings.
