Why not, it's fine. I remember my first Mafia game where clues were based on chemical elements. Now try to decipher a clue based on a chemical element. You immediately start thinking: "Ah, damn it, which guy discovered it and how is it related to that guy in the clue? Or is it related to how this element is used? Ah, maybe it's just something associative?" XD
I'm just kidding, of course, but even a list of trivial things can be used to create interesting clues.
