It's been done, but here's my shot at the old Marriage Contract type story. Harry and Daphne Greengrass find out their parents put together a marriage contract when they were born, now they must deal with it.

Petunia married a biochemist, and Harry grew up reading science and science fiction. Then came the Hogwarts letter, and a world of intriguing new possibilities to exploit. And new friends, like Hermione Granger, and Professor McGonagall, and Professor Quirrell... COMPLETE.

Enacting peace through understanding has fallen to the side. A catalyst is needed for any kind of change to occur, and it is all found in a little boy... for better or for worse. AU.
