No one here knows Christopher Tolkien (unless whoever it is has a remarkable capacity for secrecy). It is exceedingly unlikely that the Tolkien Estate would sanction this project, or even approve of it. I say this based not only on general impressions of the way matters of publication work (though this, admittedly, is from one who has never had any experience with such things), but also on the position the Tolkien Estate has taken in other matters.
