This is a good idea on the surface. It's what happens below the surface where the problem lies. But first of all, I think successful racial integration in the US is already tried and true within the upper middle class of whites and blacks. Or am I mistaken? However, mixing social classes doesn't seem to work even if it's whites with whites or blacks with blacks. Here, in Sweden, we have tried (forced!!!!!) busing school-aged Arabs into School-aged Swedish children. You'd have to plug your ears for me to tell you what happened because you won't believe me. So, mixing races shouldn't be a big problem. It's the mixing of classes or cultures that'll ignite the nation into chaos.
