The bees would still overcome the wasp, assuming it's a large hive. The wasp will have practical limitations on the amount of ammunition for the weapon (also the question of whether it can reload before getting swarmed) and the ceramic armour won't help against the bees massing together to form a ball of bees around the wasp and overheating it until it dies.
Edit: Apparently it depends on the type of bees as to whether they do the heat ball of death thing, so your mileage may vary.
Why bother with importing y'all when we already have yous (or youse depending on how you want to spell it)? Or you could just treat 'you guys' as gender neutral, it effectively is these days with how people use it.
