yeah, split the lm from the ntlm part, i think the reason why there is no such combined attack in hashcat, lm is obsolete for a very long time na dhashcat is very specialized
afterwards i would take the 7 part output and use a simple combine (combine the output with itself as the input) + rule attack (be sure there are standard rules like toggle word combined with toggle first char, as most passes will probably start with an uppercase)
i also made a simple python script which outputs every combination upper, lower, but mostly i dont need this script
you can also attack each lm on its own, this way you could see the two 7 char parts which belong to each other or you have to take a look yourself after cracking als parts
