Wedge could be played by anyone really, no one watching a new series would expect the actors and graphics to be indentical. And Wedge's face was mostly obscured by his helmet for most of the time.
It would take three trilogies to get the X-wing books onto the big screen, and even then they'd have great difficulty getting all of the action and character development into a 2 hour lot.
Still, if anyone pulled it off, it would be something worth watching
