There are several reasons why I think the analogy breaks down entirely here. But to explain so would probably start venturing into the realm of Modern Politics.
What I will comment on is the South African side of things. To begin with, South African white liberals never argued for maintaining the system of Apartheid in a new coat of paint. One idea that gained some traction is the concept confederalizing South Africa. In such a scenario, there won't be any need to put lipstick on a pig since there would be no overarching white rule over South Africa, certainly compared to before.
But that was only one idea within the liberal camp, and increasingly towards the 1990, an idea that started to fall off as many white liberals saw that already existing turmoil being too much to implement it. Thus the mainstream white liberal position was almost exclusively in favour of something closer to modern day South Africa than Apartheid or confederalism.
