Ryan, thanks for posting. We don't usually see people joining up on offers like yours. I think there are often too many mis-match parameters to make a joint trip work.
What you might do is cancel your unneeded permit on recreation.gov, and then someone else can pick it up and plan their own trip.
Otherwise, when you go to pick up the permit, the unused one becomes available to walk-ins, but most people aren't willing to drive to Lone Pine to find out what is available.
