I don't think anyone has even thought about doing this... The AW3's screen is brighter than the AW2's!
As the AW3 is so new you should try to get it covered under warranty (get AppleCare + if you don't already).

@quekilombo - Diego - The NFC unit is missing on the Series 3 display so you would need to recover the chip from the broken Series 2 display if you could to then re-solder onto the new display to get this to work. Given the sensitivity of the LCD unit and the mass of the glass this will be very difficult to do without damaging the display. Here's the back side so you can see the difference:

The Blue outline is the NFC chip and the spot on the Series 3 is vacant. I think I understand why Apple did this as replacing a broken display would invalidate the information in the watch when people had ApplePay enabled. Having it as part of the main board makes sense.
