can't be done. or do you have possibility to check in a light box that geometry produces a) good light so you can see and b) does not blind people. headlight manufacturers spend a lot of money on this; for a reason.
And with something modified in this fashion it would certainly not be covered in the headlights E-number, i.e. they would not be allowed on a public road. Blackening some of the parts that are not relevant for lighting is a grey area that you can get away with in this country only, but having a whole custom built headlight would get you fail on MOT and tbh the police should stop you as well.
why don't you just put mk4 style hellas in??
