In the Airgapped Wallet Community we also have been investigating
solutions, in particular as current common practice is is reuse the same
xpub for all multisigs, for instance [90081696/48'/0'/0'/2']

Nothing got as far as your version though.

So Concept ACK from Blockchain Commons. Less clear on your specifics

Note that we are releasing a descriptor & multisig centric iOS and Android
reference wallet soon so solving this correctly and having interoperability
with others is very important for our roadmap.
