No, it isn't.
Workers do not have the ability to choose whether to be a queen or not. That choice is made for them when they are raised. A larva cannot feed itself royal jelly. And it should be obvious that given the choice, a worker would always choose to be a queen. After all, you're related to the existing queen (she's usually your mother or your sister), but you're even more related to yourself, so anything that increases your own reproduction at her expense is a good thing. Conversely, workers, given the choice, will almost always raise other bees as workers, because they are always more related to the existing queen than to her offspring.
Wikipedia says here that workers are 75% related to their sisters. They would only be 50% related to their own children after mating with an unrelated male. So mutations that cause larva to grow up as queens without royal jelly are actually deleterious. If workers were fertile, they would still evolve not to lay eggs while the queen is alive.
