Luffy and Ussopp were so excited to go to Elbaf that I'm starting to dread the arc the closer it gets.
Vegapunk heart monitor gave out at the end of 1108 so theres a high chance Elbaf starts off with, at minimum, a distraught Franky mourning the death of Stella and subsequent destruction of Egghead (and thats assuming Luffy and Sanji take their failures well too). Kuma and Bonney will likely be there finally reunited, and both Luffy and Ussopp have a high chance of meeting their heros soon.
I'm thinking that we'll come to see Luffy and Ussopp cheering for Elbaf as a darkly ironic moment. We might see W7/Sabaody insecurities rear their head as 500,000,000 beri "God" Ussopp, and the still too weak to protect all his friends "God" Nika confront their own reputations and expectations.
Like with Ennies Lobby-TB I believe we've seen multiple examples of some Straw Hats seeding their own future developments all over Wano and Egghead.
Robin is easiest to see, but Zoro not only feels like he isn't where he should be, he straight up isn't. He couldn't knock Kaido down with his aCoC overdrive, and can't even shove tiger Zoan Lucci out of the way after an arc full of Dinosaur Zoans. Lucci even calls him out about it.
Sanji just failed guard duty and witnessed the man die in his arms as he left his Captain to fend off a demon and an admiral simultaneously. After promising a 12 year old girl, an old scientist, and his Captain he'd protect him.
Ussopp did literally nothing on egghead except get choked out by Kizaru, though he did try swinging on him. During Wano though, he watched O-Toko believe his lie about toad oil during Yasuies execution, and Nami refuse to lie to Kaido about who would be the pirate king. I doubt Oda "I can't draw Ginnys moms state because it causes me distress" will shelve that for long.
I wouldn't be surprised to see Nami related to BM/Mother Caramel or someone else with access to Sky Islands (assuming the likely possibility there is one on Elbaf). And thats without going into the potential the other Straw Hats have for small stuff.
Elbaf will be peaceful at first, and just like W7 grow more and more stressful and unstable, until (I hope) Robin inverts her role from W7 and becomes the crews rock during a rough time.
