well they could get right close towards the climax in the tower, as all hell is breaking loose anyway.

as oppose to a fighter, why not a burning star destroyer crashing into the surface of the DS (aka force unleashed trailer), maybe as it crashes down, the tower shakes and at allows for luke to charge vader.

bits could then fall from the ceiling, and more sparks would fly. it would parallel ROTS with events happening on geonosis that directly intereact with the duel, like when the shields get disabled on the platforms?
