I get where your coming from, I really do neoisak. You want your Potterworldmc experience to be as much like the experience at hogwarts would really be. Unfortunately though this idea is simply unsustainable, the amount of resource's that would go into this is more then I could imagine that would be catered to a specific type of player, that I believe would be very few. I also think sleeping and eating would simply be boring, imagine hoping on a server simply to go to bed, as I said in a past suggestion by you, eating only takes two seconds by right clicking on a plate and eating it. Unfortunely there's not very much you would be able to do, unless you got another suggestion, for making eating fun as well as sleeping. We do however already have real lessons, with real people to take the role as a professor. When it comes to roleplay you could setup your own party inside the game to try and re-inact everything your wishing to do. We already have so many amazing places and people to do that with, without creating a custom sleeping and eating schedule and most importantly a server.
