my front yard has tombstones. I like them, the are cheap and easy to Halloween it up. I go "Halloween" not classy lol. ghosts hanging from trees, which doesn't appear to be an option for you- how about something like light up ghosts lining the walk? I think these are fun
I kind of love the cheesy creepy Halloween decor. I agree that you can either keep it "Halloween" or can make it more fall generic, but the two together don't fit together so well. If I saw more people in my neighborhood with your kind of Halloween decorations, I'd be thrilled. As it is, our house is usually one of two decorated houses on the street.
