A4 Sunroof in A3?

Anyone know if it could be possible to install an A4 factory sunroof into an A3 w/o the Open Sky option?
Or, if not, any other aftermarket sunroof? I'm not too concerned about slide but would like tilt.
Would be ideal if it could be electrically operated from the A3's roof switch, at least to tilt.

I'm pretty sure that you can't do that but if you just want the look of a moonroof, check this out. Too funny.
