Even if dormant tardigrades were delivered to the lunar surface, they wouldn't be viable after a short time. Between being frozen to less than -200F at night, to roasted at 200F during the day, and irradiated with all kinds of hard cosmic radiation, any DNA present would be destroyed fairly quickly. It's surprising to me that tardigrades can survive even a brief exposure to space.
