Any other 2vs8 themes?

Maybe with stranger things they could have a 2v8 with an upside down world you enter through portals (but without gens in it, maybe for some other item based objective like the halloween event as we know how terrible vecnas map is due to portals).

Could have an aliens vs predator theme if predator ever comes as a chapter, with motion tracker devices for survivors and cloaking devices for killers or something.

A castlevania 2v8 maybe finally bringing in draculas castle map and death as a killer, with all the cosplays from the dracula release becoming legendaries. Maybe survivors get something like a blinding light cross thats a 1 use blind/stun, while killers get some kind of darkness aura that makes the area around them dark and survivors cant see where they are going in it unless they have a cross.

A dungeons and dragons 2v8 with maybe a baldurs gate 3 chapter and the event involves chests like vecnas but for stuff against the other killer as well, and the killers can get items from the chests too to track/catch the survivors easier or something.

They could have a hag + artist, hexes vs boons 2v8 where they add a boon class for survivors and a hex class for killers that can reapply hexes, while only the boon class can cleanse the hex totems, and regular totems cannot be broken.

For an unknown + dredge 2v8 they could add a "devourer" class that starts off weakened and gets stronger the more survivors get hooked (by either killer) and eventualy has a baskit devour hope effect, to prevent mass slugging survivors downed by that effect get a much faster recovery speed to ensure the killer takes priority to finnish targets. to compensate survivors could get a protector class capable of tanking hits with deadhard and oreillas protection hit speed boost.

For Stranger Things, I think pairing Demogorgon with Vecna is obvious, in an ideal world where that works out with the licenseholders.

Two Knights At Freddy's could make a solid april fools' 2v8 for next year. In an ideal world, it'd be a 5v20 to perfect the joke, but we can't have everything.

Theming a 2v8 around Trickster specifically could be a good opportunity to finally give him a map. The scale of a city inspired map kinda fits for being designed for 2v8 first then scaled back for regular trials afterwards. Could be a good chance to put Kaneki in 2v8 too.
