I will look into that, but please consider that the MK1 and MK3 are very different in some regards.
The MK3 has the longest wheelbase of all generations yet is the shortes of them overall.
Due to its short overhangs, the radiator is just about in line with the front of the wheels.
Any ducting to divert air must come from in front of the radiator as there is no space for ducing radiator exaust there.
This is why I consider using the small intakes on the sides of the front bumper for it as the ducting would be significantly less complex.

Edit:
I will also keep the frunk as deleting that would massively reduce the practical capabilities of my car.
It also needs some weight in there or it becomes unballanced.
Wich is not nice as it makes the car understeer at low speed and unstable at high speed.
