Permanent Creative To Survival Change

I would like to be able to create a world in creative mode which I can permanently change to survival, without the ability to use cheats ever again. I don't think it would be a problem if achievements aren't still available. But I have some worlds that I'd like to adventure through with my friend, and I can tell he's just not invested in it because he knows that we can change it to creative mode on a whim; so there're no stakes involved.  

So, to simplify.

In the creative mode menu, can we get an option to change from creative mode to survival mode without cheats, permanently? 

I realize it might be prudent to include one, maybe even two levels of security by warning the player that there is no going back to creative mode or using cheats, and that achievements will still be unavailable.
