True but with enough work they "should" fit. There's a guy with a Bravo who has fitted (with a little bit of work) MK2 Punto headlights onto a Bravo. Should have thought the reverse would work too.
I can see where you are coming from. It will have to be a custom fit job, especially if you want the auto levellers to work. The indicators are very much forward facing so you may have to put some side repeaters back on.
Good luck, it should look great if you can pull it off.
