Only problem with Burbin’s line is that Luke’s statement needs to end with a direct mention of Exegol so that Rey can respond with, “I can’t get there.” And the order of shots dictates Luke having to mention the thousand generations before then saying for Leia’s legacy to guide her on Exegol.
Also, JJB, I prefer the delivery of 3PO’s lines about needing a mechanic that were already used in V5 over the updated ones you provide. If you want to try again I can consider alts, but in a direct comparison the old one fares better to me.
