Here’s a suggestion for a new version. In the novelization of the film, during Rey’s Force vision, she hears a voice, that I believe is very likely Kylo Ren’s voice.

"Once more she climbed to her feet, her chilled breath preceding her. From in front of her, not far away, came the sounds of battle: the cries of the wounded and the clashing of weapons. Then behind her, another voice. That voice.

“Stay here. I’ll come back for you.”

She whirled, glazed eyes desperately scanning the dark gaps between the slender trees, trying to penetrate the darkness. “Where are you?” She started running toward the voice

“I’ll come back for you, sweetheart. I promise."

What do yo think of the idea of getting a sound alike voice actor that can sound like Adam Driver to read out these lines for that scene? For example, when she looks down the hallway in Cloud City, she hears the first part. Then she hears the second part when she runs into him in the snowy woods. The second part could play out like this.

OBI-WAN: Rey.

KYLO REN: I’ll come back for you, sweetheart.

He appears in front of her with the lightsaber. You hear his last part when she stumbles backwards.

KYLO REN: I promise.

OBI-WAN: These are your first steps.
