another way to look at it ..
If the Beetle was backed up in the photo until the windshield was at the profile's start, it would shorten the length a fair amount.

I could leave the windshield as is and hack just the roof and hatch.



I could shrink the car into a boat tail

edit: It would require a Roll Cage and certification and more money then I have to spare at the moment. mo money
Here's an image adapted from Koenig-Fachsenfeld's book.The fourth image down depicts a body who's roofline descends right from the windshield header.
I can't vouch for it.It's never done,even in racing cars.There's always a 'soft' peak,where the boundary layer is given ample time to reverse its camber.

Volkswagen corrects the Beetles roof some with the Audi TT.
They take it further with the Porsche Panamera.
VW's best (in elevation)is perhaps the Bugatti Veyron and the latest Lamborghini's,like Aventador.
All have very forgiving contours to protect against separation,as this would also induce rear lift.Something potentially life-threatening in the supercars.
While you're waiting on cash for the project,check out VW's high-end cars,and also,Freebeard has done some really nice renderings of Beetles with modified rooflines.Well worth the look.
I've got 37 scans waiting.If Al can do them,I'll have some additional images to share.
