well hashcat could do this for you on the fly without any need for a premade wordlist
bruteforce and mask-attack is more or less the same, you can use a masks like ?a?a?a?a?a?a?a?a?a?a to mimic plain bruteforce
also you can tell hashcat to start with 10 chars minimum, but luks is considerd slow and bruteforcing will be for sure not really sucesssful
try running hashcat -b -m 14600
and see your guessing rate
