I don't think that's what anyone was saying here. Han loses his biggest benefit (going First) if you do this.
Luke synergies nicely with Yavaris, as part of a larger shield-piercing or bomber strategy; I'd probably base such a list around Dutch, Wedge, Luke, and B-wings. But it's not as simple as plopping the models on the table and hitting the IWIN button. It's a good combo, certainly, but there are lots of those in this game.
