Things were the way they used to be for good reasons.
I’d say blow the whole thing away, but at a minimum, get rid of the special scrutiny for the southern states. The South has been growing at an incredible rate, and the population is entirely different than the Jim Crow era that the original bill sought to punish in the 1960’s. That you would try to accomplish equal protection under the law by discriminating against specific geographies is absurd. That SCOTUS has supported it for 60 years is an embarassment.
