You could do that by calling vec on it. But you'd want to move the whole let clause outside of the defn, so it is only evaluated once, not every time the function is called.
But best, as I said earlier, is just to let chars be "0123456789ABCDEF". You can call nth on strings, so this is the most efficient way to do a fixed sequence of specific characters.
