I will admit there's potential there, because of the burning question of not why Slytherin was such a scumbag (remember, he didn't just "hate" muggle-borns; he actively plotted their eventual genocide with the whole "heir of Slytherin" business), but why the other three were willing to work with him. Real history is full of people who are not villains but, by our modern standards, would be considered extremely problematic, and our society is increasingly struggling to reconcile that with our desire to celebrate their accomplishments. (Not to get too much into P&R territory but yes, Virginia, there are people who unironically suggested tearing down the statues of Washington and Jefferson alongside all the ones of Confederate soldiers. I was there.) You'd need a hella talented writer to pull it off, but this is one subject that the Potterverse's central racism analogy could be used to deal with.
