FP4+ is a traditional B&W film. Your local lab who only processes color film won't be able to an adequate job. His machine is not calibrated for it either. If you are going to do that, you might want to use C41 based B&W film instead. Both Kodak and Ilford has one.

You could reduce the development time and reduce the contrast but yes, you will end up with low contrast negative and you'll have to compensate for it when you print in a darkroom. You shouldn't have to compensate your processing to tailor your lab. That's the other way around.

Beyond that is pretty much off topic for APUG.... as will need to talk about hybrid process.
