In our game I allow aiming to bypass armor/soak. Especially on a landed ship, there are all sorts of exposed bits and pieces that would normally be covered, and a personal weapon against a large, stationary target should have no trouble finding a weak spot. Hell, finding the weak spot in an otherwise unhurtable target is about as Star Wars as it gets.
Potentially some risk with more hardcore number-crunchy players, but we have a relatively light cinematic game and this works out well.
