If the sails on at least the main sail barge are enlargened (or a bigger sail is added), as well as ropes to "tie them down" like regular sails on a sailing ship, a shot could be added to show one of these sail posts being destroyed, with said sail and post falling to one side. The Luke/Leia have an extending pole from which said rope can properly swing from. Of course, showing the sail barge list towards the sarlacc pit and Han's skiff would help too.

Maybe another slightly larger version of the two sails could be created to overlap above the 2 sails seen here.

Of course there is nothing saying that Luke just uses his jedi powers to levitate Leia and himself over to Han's skiff...

You know, come to think of it, I wonder why they didn't have Leia kiss him on the cheek and say "for luck" again. It's not like Lucas took anything else from ANH when doing JEDI.
