I don't think Luffy needs a gear 5 but if he has one I hope Awakening is his gear 5.
Luffy and Zoro's "power boost" for Wano is about improving their CoA haki.
Zoro learned how to produce more powerful attacks by using more haki and less physical strength. With enma Zoro can improve that skill much faster.
Zoro cut a cliff using only the physical strength needed to cut a tree thanks to his overwhelming and powerful haki/ryuo
Luffy learned flowing haki and internal haki. He
made a tree explode from within without physically touching it thanks to his powerful internal haki attack.
Right now, they're still working to master their powers and it's making things more difficult.
Zoro still hasn't fully master enma and until he won't have full control over his haki and it's going to drain his haki faster.
Luffy is using internal haki with his G4 which drains him too quickly and puts too much strain on his body.
Once they master their powers they will be much stronger. So instead of Luffy gaining G5 I hope he uses G2 more and put all his gift for power and strength into his internal haki G2 attacks. When Luffy was hitting Kaido with his kong gatling I feel like 80% of the AP from from his punch and only 20% came from his internal haki.
