Because something is overused, does it mean you can't write about it?

I like werewolves and have been wanting to write a fantasy book (or series) about them for a while. They are nowhere near as close to being as overused as vampires, but people still say that they've seen more of werewolves than they can handle. When I try using witches, faeries, genies, dragons, japanese mythical creatures, etc. it doesn't work. Nothing comes to me. So my question is this: even if werewolves are overused, is it still okay to write about them? Will people still read it? I have no intention of writing another werewolf paranormal romance, putting my characters in high school, or putting them in the midst of a vampire-werewolf feud. In fact, vampires will be extinct in my story and the werewolves will be more like "wolf gods" (think Holo from Spice and Wolf) than traditional werewolves.
