    BUT... if this is an optical system involving one or more lenses, it may be far more complex than that. I would imagine if the slit is placed in image forming plane (there are multiple of these in a complex lens system) or elsewhere, the result will likely vary.

    If it is at an image forming plane, you might actually get a image with only visible part being where two slits are.

    You cheated first by amending the original setup!
    But the main point here is observed with film, or not observed.

    i sometimes forget to put film in a camera, i go out expose it, and process it.
    it ends up being the same image on the non existent film that i thought i had.
    Reminds me of the Steven Wright joke:
    "I've been doing a lot of abstract painting lately,
    extremely abstract.
    No brush, no paint, no canvas,
    I just think about it."

    It won't matter, at the quantum level Heisenberg screws you every time.
