I'm not saying this to be racist but I don't think it would make sense to have Caucasians or non-blacks and The Dreams. This is because their race is sort of essential to the plot so changing the race would affect the whole story. If race was not an issue, I would not mind a non-black The Dreams. However since race is essential to the musical's story, changing the race would be unwise. I mean, with a musical like Lion King race does not matter so anyone can be in it whether white, black, Asian, Hispanic, etc. But The Dreams can only be black. Non-blacks can still have a place in Dreamgirls, but not as The Dreams. It just would not make sense.
