I just thought of something:

Commander's abilities would rule on the Death Star! It'd go something like:

Wedge [in trench]: Almost there...
[Targetting computer counts down to zero and locks on. Wedge fires both torpedoes]
Wedge: Weapons away (or whatever it is he says )!
Yavin IV: Did it go in?!
Wedge: Negative, I repeat negative, it did not go in this time either. The exhaust port's still plugged shut by the supply crates and Jeeps the Imps keep spamming down it.
Yavin IV: Curses... we got any fighters left?
Wedge: Plenty. The Imps keep trying to grief, but the platform we spawn from is above the spawn altitude of their artillery shells!
Yavin IV: LOL!
Luke: OK, then, I'll give it a shot. Wedge, you're the commander, just keep spamming the exhaust port with artillery until we win this game.
