The problem with this is that there's still a floor for most people regarding age, and only so much sleight of hand he can do to disguise their age. He could make the apostles look 30 years old, but if they're literally being taught about the birds and bees and other rudimentary concepts, it isn't going to change the fact that they're designed to be very young. I think all of us let Ellie and Dylan slide, but for me I can't do that twice. We know that Dylan is on the young end of what most people would consider "too young", but I choose to look the other way. But the apostles are even younger than Dylan, and so it just becomes a bridge too far.
This doesn't even touch on the issue of Sophia's lightning fast corruption with them.
