It would have to be one enormous black hole for it to be possible to cut parsecs off of the slingshot distance around it. You would barely feel the gravity of any stellar massed black hole from even 1 parsecs away. Also, wouldn't relativistic effects mean the trip would actually take longer if the trajectory cuts too close to the event horizon?
