Instead of Ben talking to Luke during the Death Star run you could have Dave Bowman saying, "My God, it's full of stars".

You could cut out the battle altogether and have Luke mimic his father by taking out the Death Star with a lucky shot fired while approaching the station.

The squad could reply to their call signs and then Luke fires and the torpedo hurtles towards the station, skims down the trench, goes right into the exhaust pipe and blows up the thing without any Rebels getting hurt.

Han could then turn up and congratulate him on the great shot.

The pilots could just fly around for a bit and go home.

Porkins could eat a pork pie.
