Sort of. It is only possible if you have USUM, because only wild Blisseys can sometimes hold Lucky Eggs. You will have to encounter Chansey and SOS call chain it to get a Blissey, which further only had a 5% chance of having a Lucky Egg. You can use a move like Switcheroo or Thief to steal the Lucky Egg, or you can try to catch Blissey. Once again, this is only possible in Ultra Sun and Ultra Moon, so once you get a Lucky Egg, you can trade it over to Sun and Moon.
