Making conversation here and opening up to some questions I have about multisig as a noob ...

Can you do a multi sig with different hardware wallets?

Or ... is it reccomended to have the same hardware wallet?

... once you make a multisig system with, lets say 2 of them, can you make a third one... fourth one... etc??

Is there an "Inhheritance Family Security Model" that you have read / investigated?

Thanks!
