Wallet Recovery – Is it possible to generate a password from a decrypted and encrypted bip38 key?

I created 5 bip38 wallets on bitaddress.org, all with the same password. All generated keys start with the number 6.

I loaded bitcoin into each of these addresses and then later decrypted one of them with my key and password to get the key starting with 5 and then swept through the addresses.

A few months later I forgot my password and my bitcoins were still in a different address. I still have the key starting with 6 and the key starting with 5 for the wallet I decrypted. Can I somehow use these keys to generate a password? There isn’t much BTC, but you can do it with cash now. Anyone have any ideas?
