Are LMP1 cars too fast over GT cars in LMS/ALMS?

Looking at how much faster the LMP1 cars over GT one has to wonder how much of the speed difference between GT and Prototype contributed to the Audi crashes at Le Mans. 

Now I'm not for making LMP1 slower, but maybe GT should be given a boost? It's a little embarrassing when they were doing the comparison between the Corvette racer and the Corvette street versions and pointed out how much more HP the street version had. Of course the race version has big fat tires and other race specific features so it would still get better lap time vs the production version but I wonder how badly the race version would lose in a drag race between the two? 

I found following data for the LeMans GT2 Corvette C6.R.

470hp

weight: 2745lbs

5,8hp/lbs

Street Car C6 ZR-1

638hp

weight: 3333lbs

5,2hp/lbs

I think in a drag race both cars would be kinda equal. cause the street car has longer gears and more power, while the racecar has shorter gear settings. and because of the tires the racecar may have better traction.

The only problem I see is that the GT1's are faster than the LMP2s. The way to fix this would be to add additional downforce to the GT1's but that's pretty much impossible if they plan to both keep the cars homoginated from street cars and keep the aero sensible.

There was an interview with one of the older drivers who asserted that they should let the LMP1 cars go 250Mph down the straights! He said they did it way back when (and admitted they were crazy because their feet was a couple of inches from the road).

Makes one wonder what kind of race would result if you had an open rulebook (at LeMans). Restrictions for LMP1 would be height, length, width. I wonder what would be the natural engineering result?
