Nucs are shipped all of the time, just have to have plenty of ventilation and enough bees to cover the brood. 'The bees covering the brood will regulate the temperature and feed them. Just my opinion but I would not ship bees in this hot weather.
There might also be laws in your area concerning shipping any live bees.
You can't ship sealed brood frames without nurse bees to keep them warm. So basically you'd be talking about shipping something similar to a nuc, either with or without a queen.
