this method works for generating any combination of multisig or single sig. I've used this method to create 6/10, 2/3, 3/5, etc. After generating the initial seeds, they can be combined using Electrum for the multisig. I do this part using Electrum because I want to have verified and documented repro steps for non-technical family/friends to recreate after I die.

Ultimately though, waiting to build a good MuSig2 setup as I'd like to move the 6/10 multi-state/user distributed shards to a MuSig2 design during a low fee time.
