The wiring could be repaired or replaced; you might be able to get a non hid headlight assembly and swap out the missing lens. I haven't seen the hid headlight assemblies but it worth checking, because of the high cost and scarcity of replacements.
What year, model is your new beetle? You might post up photos of the damage to your wiring harness. Have you had any luck, looking for replacement parts, using the part numbers off your old damaged parts?
I have used the tunemyeuro replacement harnesses; you might see if they are compatible or make you a new one that works, for your application.
Check with your local vw dealer and see what they sell new ones.
Also, there are specialty automotive wiring harness repair shops and that is another route, if the costs from your VW dealer are really prohibitively expensive.
