Here’s the current dialogue of the Jedi Voices. I hadn’t realised there’s actually a very nice trajectory and build up over the course of the dialogue; it’s not just random snippets of generic encouragement. I’ve tried to keep that same flow, and added my own suggested lines in bold:

OBI-WAN: These are your final steps, Rey. Rise and take them.

ANAKIN: Rey.

AHSOKA: Rey.

KANAN: Rey.

ANAKIN: Bring back the balance, Rey, as I did.

LUMINARA: In the night, find the light, Rey.

MACE: You’re not alone, Rey.

YODA: Alone, never have you been.

QUI-GON: Every Jedi who ever lived lives in you.

SORS: We are all one through the Force, Rey.

ANAKIN: The Force surrounds you, Rey.

AAYLA: Let it guide you.

AHSOKA: As it guided us.

MACE: Feel the Force flowing through you, Rey.

ANAKIN: Let it lift you.

SORS: As it carries us.

ADI: Rise, Rey.

QUI-GON: We stand behind you, Rey.

OBI-WAN: Rey.

YODA: Rise in the Force.

KANAN: In the heart of a Jedi lies her strength.

OBI-WAN: Rise.

QUI-GON: Rise.

LUKE: Rey, the Force will be with you.

LEIA: Always.
