Seems like you want to try PolicyGen of PACK (Password Analysis and Cracking Kit): http://thesprawl.org/projects/pack/#policygen
--mindigit 2 , --minupper 2 etc

also see .hcmask description: https://hashcat.net/wiki/doku.php?id=mas...mask_files


(BTW: it's still way too large keyspace, the few possibilities that are skipped are negligible compared to the huge keyspace)
