Oda really should have given us full fights with the VAs against the weaker SHs
It's possible we'll get this in Wano. Teach is about to move on Pluton, and there's an entire Marine Fleet just sitting there post-Egghead, waiting to fight him nearby. The Big Buster Call Fleet got their ass handed to them, I'd imagine a lot of the ships from Egghead went to G-14 afterwards since it's nearby, for repairs/medical attention.
I was always under the mindset that Egghead was a 2 part mission:
1. Send CP0 to kill Vegapunk, and retrieve the Seraphim
2. Marine fleet arrives to take the Seraphim to Wano to annex the country, like the Gorosei wanted to do post-Onigashima (until Zunesha showed up and Momo decides to not destroy the borders)
Hell, Kizaru and Saturn arriving like, a day after CP0 makes me wonder if the WG was trying to kill off CP0, too, since they had authority chips a grade under Sentomaru, and two grades under Vegapunk; Lucci and Kaku already rebelled against the government during CP9's Independent Report Cover Series, and as such they should not be on great terms with the Gorosei. IMO, between Onigashima, and Egghead, CP0 is on the way out; too many failures.
Think about it; if Lucci and Kaku rebelled again, this time, they're Awakened Zoans creeping towards Admiral level, and, because of their background, they'd most likely become Pirates. Not worth the headache. Also, what did Lucci prove during Egghead? That he puts his bloodlust before the mission/orders, he put fighting Luffy above his job.
Green Bull jumped the gun, yeah, but he also said it best: No one was ducking Wano because of Samurai, it was because of Thunder Baguya Drunk Dragon Man. If the Straw Hats weren't there when Aramaki shows up, he takes over the country by himself.
Once Kuzan tells the Marines Caribou told teach about Pluton, a clash over Pluton between the two parties is inevitable; the Gorosei sent half of CP9 after Robin in the past. Like hell they're letting Teach get Pluton when they've got how many forces stationed nearby?
We should see the 9 VAs in action again sooner rather than later. Doberman's cool, I want him to do something other than babysit Saturn's terrorist ass. Also I want to see how Guillotine fights just for my own amusement, weird ass design. My guess is he Geppos into people to try to decapitate them.
