Hypothetically, I think I'd structure it somewhat similarly to season 5: a couple of episodes to establish the stakes, two or three more to gather information or materials, then a couple to put the plan together and enact it, and then ideally at least one to catch up with Zora after the events of "Calpyso."
As it is, there are so many unanswered questions surrounding this mission that I hope we at least get a novel or something out of it.
