Here’s an idea - Use part of the Kylo prayer scene between the interrogation and the rescue. The reasoning is that during the interrogation, Kylo might have picked up on Poe’s memories of Leia. There could even be some dialogue of her from the deleted scenes: “Poe, if they get to Luke first we don’t have a chance.”
Then just have a couple lines from the prayer scene, keeping the helmet reveal for later: “Forgive me…I feel it…the pull of the light. Show me the power of the darkness.” Then the vision of the Starkiller would be here instead of in the interrogation, along with the First Order theme music making its first appearance.
This would also explain why Kylo felt the need to give Hux the responsibility of going after the droid instead of doing it himself.
