Personally, I don't feel like Leia is worth it in 150 point games. For those same points, you could fit in another Ossus Guardian, or a more beefy piece like Jaina. In the first squad, I could see using Leia there, because you don't have Wedge. But I think in 150 points, if you're going to run Wedge, adding in Leia means that 1/3 of your squad is just tech/support...that's way too much for 150 in order to be competitive. For the 2nd squad, all it would take is one lost init in a key situation, and you'd lose Mara, and thus probably the game.
I'd work in a 3rd threat for the 2nd squad instead of Leia. In addition, Mara's Stealth means that only Accurate Shooters can target her, so a single Evade + FP re-roll if necessary should be more than enough to keep her alive.
My favorite NR squad at 150 points right now has neither Leia or Wedge, just as a point of comparison.
