Halloween // Looking for an interesting couple costume idea

So my wife and I have a halloween party end if october and I wanted to do a casual Jack Skellington however shes not very interested in being sally. So we came up with the idea that she could be another Tim Burton character like corpse bride, or something similar like the other mother from Coraline.

She also pitched another female character opposite a horror Jack, like wendy from the shining. So what other Jacks have female opposites/partners or what other ideas do you guys have to match to a Jack Skellington

Thanks for your time!
