I think this is an interesting setup just because it makes it possible to have a very complicated 1Password master password without being too inconvenient. For my use of 1Password, it wouldn't work though since I use it on my phone frequently. However as others have said, you need to have a way to get to the full password somehow, likely in the form of it written down and stored in a safe, at home or in a bank. Or in somebody else's password vault. Actually, that's something I haven't seen much and that I have done myself manually only: the ability to secure this information by spreading the database with multiple trusted parties. Similar to what Snowden has done I understand: no-one can access the information by themselves, but you can piece together whatever information you need from multiple people. I know some stuff exists like this, I just haven't seen for password vaults specifically.
