Yes, that would be ideal. The problem is her role in Finn / Rose’s arrest and the climactic moment of Holdo’s suicide attack are inextricably linked. I don’t think there’s a way to do it convincingly. It was silly to bring her back given her arc with Finn was complete in TFA and should have died on SB. Since they brought her back to be a familiar face among the storm-troopers, though, I’m okay with her going about her duty and this time being beaten by fate. Holdo’s shocking maneuver was a more satisfying victory for the rebellion in this moment, and I didn’t want/need Finn to have another showdown with Phasma, which by comparison, seems like small potatoes. I’d also rather Finn express his commitment to the rebellion through his other actions in the film.
