If you take care of the chunking I guess it will work fine.

I think if you combine following Forks you get a good head start

ByLamacq has implemented the Vectorization Patch
https://github.com/ByLamacq/BitCrack/commits/master

BoGnY and his OpenCL Fix
https://github.com/BoGnY/BitCrack/commits/master

Fishpeppers Base58 Patch
https://github.com/fishpepper/BitCrack/commit/af2aa3e2df798453338b71f619f2596620a600a5

And you would just have to apply the changes manually without knowing that much of c++.
