How likely will we get Hell's Chicken/S.E.A. BokGak?

Seeing how the other events are getting future reruns, I wonder if Hell's Chicken and S.E.A. would get one in the future. Hell's Chicken already has a hard mode version of it's boss, so it may get a even harder mode if it's changed.

As for possible event-exclusive IDs/EGOS:

Hell's Chicken: Maybe 'Eight Chefs' Greta, from before she Distorted. Or even after. Other option could be Backstreets Butchers IDs. It's a bit difficult to think of a related EGO, so I'm just spitballing this: Nameless Fetus (obsession with eating).

S.E.A.: Definitely Molar Boatworks and Molar Office IDs based on Mika. For a EGO, 'The Naked Nest' due to it's similarly to 'Whales', or 'The Dreaming Current' due to it's similarly to 'Mermaids'.
