Tried the following btcrecover commands given to me by one of the devs at xcubicle working on this asset recovery with me:
python btcrecover.py –tokenlist my-wordlist-pattern.txt –wallet
mywallet.txt –blockchain-secondpass –no-dupchecks –no-eta
–tokenlist is just a text file with all your regex patterns. I tested a few different patterns from the btcrecover docs page. Ex. %8p (means 8 characters digit or characters)
–blockchain-secondpass — requires you to know your 1st password first.
–no-dupchecks — this is to disable a check
–no-eta — if you dont specify this, max-time is 168 hours and it will error out at the end of that time.
