It would be fun to combine two different oc killers into one killer to make the "ultimate predator"
I think it would be interesting to do an event that is like "killer fusion" where two original killers are combined to make a new killer, but with some form of both abilities. Or perhaps a new ability that is some kind of combination. For instance, Nurse/Huntress would have nurse's blink and huntress hatchets. The character would visually look like a combination of both characters, say nurses face covering but huntress build. Or Wraith/Blight, a killer that can both speed rush and be invisible. Or Billy/Trapper, a killer who has a chainsaw but can also put down traps. Dredge/Unknown, the ability to have nightfall, pop out of lockers and leave behind mirages, etc. Hag/Plague could both set traps and shoot vomit. Clown/Deathslinger could throw bottles and shoot his gun.
There would even be a place for it in the lore, as we know Blight likes to experiment on other killers, hence the different blight serum cosmetics. Maybe the entity wanted him to make the ultimate killer?
Anyway, it might be an interesting way to experience a new form of gameplay, and make for some interesting and challenging games.
