Narrowing brute force

[slyexe]

You're completely right, you can diminish your attack significantly. Take a look at https://github.com/iphelix/pack. However, a single card attempting to crack anything over 6 characters you will most likely never accomplish in this lifetime. That is a issue with bcrypt is to prevent it from being bruteforced.

Either try remembering as much of the password as possible, create a wordlist and play with rules. Otherwise, you're looking at renting/purchasing more hashing power which will be expensive.
