This is how I see this arc going.
Small skirmishes between Vegapunk and Strawhats, and Sword vs Strawhats.
Smoker, Tashigi get some action, some Seraphim get some action, Helmeppo meets Luffy and talks about Koby, Straw Hats vs a bunch of crazy mech animals.
Then, CP0 shows up, and reveals Vegapunk's actual goals. The Straw Hats then protect Vegapunk from CP0.
Then Blackbeard invades thanks to getting information about Egghead by using Laffitte's hypnosis of Koby, and we get a bunch of Zombies resurrected with the Shadow Fruit fighting animal-mecha and giant robots.
YEEHAW TIME FOR SOME SCIENCE
