Yes. It’s thematically linked more than logically. The same point could be made about Luke in ROTJ; presumably, the team would have destroyed the Death Star regardless of Luke’s success or failure onboard.
Unrelated: I don’t think Threepio’s like has a place in the briefing scene. “Without the Republic fleet, we’re doomed.”
On the Threepio line, I interpreted his meaning to be a more of a general ‘without the Republic Fleet, our paltry dozen X-wings are doomed’.
There’s an important difference in the Starkiller attack, since the bombs allowed the oscillator to be destroyed. Arguably, if they’d done that sooner instead of confronting Kylo, they would have saved the Republic. Luke was ready to ‘fail’ in his quest since the Rebellion’s mission was entirely separate.
But I agree with everyone that V1 should stay. I made some changes to the mockup, but I don’t think they’re sufficient.
