I had this idea of a 12 word seed as key.

So I looked at the Sheakspeare poem: https://www.poetryfoundation.org/poems/45085/the-phoenix-and-the-turtle-56d2246f86c06

And tried to match words with the BIP39 wordlist: https://github.com/bitcoin/bips/blob/master/bip-0039/english.txt

But I got too many words making impossible to try all combinations.
