Why do you assume that the current 24-70/4 IS is that much worse compared to the 24-70/2.8 II? As I see it differences are marginal and mostly copy relevant.

have a look here.

That's one copy of each lens which hardly relevant and compelling.

The-digital-picture.com has tested 4 copies of the 2.8 II and 3 copies of the 4 IS and except for a slight difference in corner sharpness there's very little in it:

Switch to 50mm now, which is the reason this is discussed here. The compare the vignetting even to the 24-105.

...from the 24-70 / 4L IS at 50mm f/4 for all three copies tested. Even the 24-105 / 4L IS fared better. Thus the point of this poll: would anyone be interested in a 24-70 / 4L IS II that performed at least as well as the 24-70 / 2.8L II stop for stop if the size, weight, and price were closer to the current version than the 2.8L II?

No. Instead I'd probably be interested in a sharper and more consistent copy to copy 24-105/4 IS II. 70mm is just too short to be a true all-round solution while F/4 is too slow for event work.

I don't see who would buy a 24-70/4 IS II at F/2.8 weight and money even if the sharpness is there.
