So, as a security point of view, it's not acceptable. I'm not shure at all if I understand correctly what you have in mind, but to unlock a LUKS/dmcrypt partition, you have to provide the correct passphrase/keyfile. If you do not, there is no way other than bruteforcing it or an attack towards the encryption itself. The master key itself stays fully encrypted.
