The Mulsanne was the key feature of Le Mans. It dictated the focus, and therefore the car's setup, for the whole track. Also, the tire loading issue is a moot point, as the cars now are set up such that they make nearly as much downforce at 150mph as the cars used to make at 240mph. And none of the current Le Mans cars have flat bottoms, so the risk of lift-off is MUCH lower than in the past.

What Mulsanne corner would need is a substantial tire barrier in front of the hard wall, which would take care of a lot of the impact force. If what is there is acceptable now, then we're already 70-75 percent of the way to being able to handle the impact forces if the chicanes weren't in place.

Finally, I'd like to note that, with the V10s, F1 cars were hitting around 230mph before the first chicane at Monza. Along the same lines, the higher classes of "touring cars" hit 220-230mph heading into Teirgarten at the Nurburgring (and that's with heavier cars and MUCH less runoff than at Mulsanne at Le Mans).
