He shows that he has embraced the idea that they can no more gain eternal life than the rich young man could—but with God all things are possible.

No, Peter is not in Matthew 19:27 saying that they ought to receive life, for in their case wealth is no hindrance given that they had already left everything behind. Rather, he is inquiring what the consequences of their actions will be. One may therefore speak of a type of holy curiosity here.
