I see what you mean. Another idea I had once about that sequence was to perhaps separate Wedge from the Falcon-- follow Wedges attack, swing around and exit completely-- leaving the Falcon in the core-- then cut away to something else (The Vader death scene)... and then pick up on Falcon's attack/exit.
That way Wedge could fly out of DS2 long before Lando got out and tension could mount more Lando's narrow escape.
This would actually raise tension across the board since everything would remain at the climactic moment for longer.
Maybe the Vader scene is too long for this, though.
