take a look at https://github.com/hashcat/hashcat-utils/releases
tool splitlen
take the mentalist english wordlist, lower its content with an editor of your choice, use linux oder WSL for sort file | uniq > file_uniq and split this uniq list into its parts
so you have lists from length 1-9
so possible combos would be
1 9
9 1
2 8
8 2
3 7
7 3
4 6
6 4
5 5
the problem, there is no attack for combining 2 wordlists AND a mask so you have to add the numbers yourself, use hashcat with --stdout to generate 9 new lists with numbers appended, so you have lists 1-9 and lists 1-9 with appended numbers, mentalists eng_dict is ~2.5mb so you will end up with a needed maximum storage of 2.5GB, which is far from your 700tb
then use combinator attack https://hashcat.net/wiki/doku.php?id=combinator_attack to let hashcat do the combining work (no need to build the whole list) so you end up with 9 runs of combinator attack
have fun
