1. Said friends have no need to know who each other are. They only need to know their role to deliver a package to designated individuals.
2. The shards they hold can only be used by the recipient via hardware they have physical access to. They can not collude without the recipient. I also trust the, far more than any potentially malicious bank insiders.
3. Wills can take a long time to process and bank accounts can be frozen for months following the death of a spouse. I want a plan that gives those I wish access to capital as soon as they are in a safe location to receive it and get the bulk of it stored in a coercion resistant way with a new quorum.

Sounds like multiple points of failure right there. From lost/faulty hardware to friends passing away. If your scheme relies on every single one of them having access to working hardware of sorts and being alive and well, that's an elaborate way to setup for failure, but maybe I just completely misunderstood your setup there.

I don't see how that's a problem given that your scattered group of friends needs to verify your demise and somehow get on a quest to gather the key shards without even knowing of each other's existence (again, I could totally have misinterpreted your scheme here).
This all sounds more like a D&D questline to me than a solid plan to ensure your assets get to the right people after your passing.
Why would said individuals need to know who each other are. They should all act independently of each other and simply hand off their payload to the recipient.
Assume the individuals in my scheme are all lawyers at different firms around the world that all have instructions to hand an envelope they do not know the contents of to designated individuals in the event of my death. This is a well understood scheme. I just do it with a redundant quorum so I can avoid any one lawyer being able to consume the contents of said envelope themselves and tolerate some of them failing to perform their duties.
As far as the hardware the recipient has access to, that can be duplicated to any similar off the shelf hardware via a 24 word paper backup and storing paper redundantly and durably is a solved problem.
These schemes use well understood standard cryptographic protocols as well. Shamirs secret sharing and bip39. The rest is just human logistics.
