Taproot should make this possible.

You could specify multiple spending conditions each with some of the required keys.

Or even better, you could say A can only be allowed to spend if B can sign too (multiple keys) or C can always spend (master key) and any other key can spend as long as it gets signatures from 3 other keys for example.

Also much better privacy for the multisig quorom.

Probably something even better could be done with musig 🤔

What could a multsig of the nation state level look like using frost or musig??
