Would it be better if I were to replace the rocks behind Luke and have him fade in totally independent of the surroundings?

I’d like to see what that would look like but I honestly prefer letting the scene play out without fading in luke at the beginning like the previous iterations mainly because the blur-in makes it look like an illusion within a dream and maybe it would give away the fact that Rey is just generating a fantasised version of luke which I think should be kept for TLJ as a shock when the audience finds out that he is just an old hermit on a rock.
