Or, in that scenario, Leia could be the one who saves her nephew or whomever from falling to the Dark Side, destroying himself and taking others with him. Luke doesn't always have to be the primary hero...each of the first two trilogies had different lead heroes, so even though I've loved Luke's character since I was a small child I don't know why he'd have to hog most of the heroic attention in a Sequel Trilogy.
In JEDI, when Luke tells Leia she's his sister and Vader was their father, he tells her that in time she'll learn to use her Force powers like he and their father did. Episodes VII-IX could be the time for Leia to shine after three films where her brother did a lot of the heavy lifting in the storylines.
