I'm thinking Halloweenmas.
You know, you leave a few Halloween decorations up. Maybe add a few skulls to your Christmas tree. A few Nightmare Before Christmas decorations should work nicely. You can throw in some Krampus stuff and *boom* you're done.
Never-mind, pay no attention to me. The neighbors think I'm weird enough as it is ... Go back to your Coca-cola Santa and elves.
