Mnemonic phrase are not passphrase, passphrase are passwords used to protect seed phrase, and to every passphrase generated from the same seed phrase, a different seed is generated.

As for the question, I am still new to wallets and BIP but with all your explanation, you have nothing you remember to even recover back the wallet, no email, even the seed phrase are not remembered, you may not be able to recover back your wallet.

Blockchain chain support only five cryptocurrencies  now, at the time, it is possible it did not support up to five cryptocurrencies, if you still remember the private keys of the funds stored on your wallet at the time, you will be able to recover back the coin using the private key on a newly created crypto wallet.
