Pelican Bar (Black River) and Treasure Beach or Pelican Bar and Y.S. Falls would be a nice trip. However, even though it is surely possible, doing all three will require a lot of time and won't allow you to actually chill for a good amount of time and enjoy any of them. Remember also that Y.S. is closed on Monday. At least it used to be so check first.
Perhaps putting a fishing boat tour (not the Swaby Pontoon Boat) up the Black River Morass could be substituted for either the Treasure Beach or Y.S. leg. Since you need a boat anyways to go to Pelican Bar, working out a price for both the trip up the river and a roundtrip to Pelican Bar would be advantageous. The fishing boats are located on the side of the river BEFORE crossing the Iron Bridge.
Just my opinion.
Peace and Guidance.
