Maybe they can. Everyone was originally a human in some form or fashion, across the game lines. Apparently anything that makes you no longer a pure vanilla 100% natural and pristine human also means you're considered a Sleepwalker. A minor template like ghoul, or a major template like vampire, or a supernatural merit like psychic powers or thaumaturgy, all sound as if they make you qualify as a Sleepwalker.
So it's essentially just the exact opposite of those merits that say they can only be taken by 100% pure vanilla mortals.
I'm sure someone will think to ask about that sooner or later, though, and we'll find out.
I wonder if that will just be updated to something like "Relating to disbelief". Meaning that hey are not true sleepwalkers but they don't cause mages to have all the drawbacks a sleeper would.
