Probably more complex than you would think - you would need new fenders, hood, bumper - basically the entire front clip as well as the electrical modifications to "fool" the BCU into thinking the advanced new lighting system is there when it is not. You'd also have to somehow reverse engineer the computer into being able to turn the lights on/off, high beam, etc.
I just picked up my new 2025 and I like the new nose way better than the original nose but I suppose that's personal preference. I could see why those who have white cars may not like it with those large black fake inserts on the front but it looks great when you have a color that nicely complements it.
