WI: Robert Curthose marries Margaret of Wessex

If you're talking about Saint Margaret then no. She's already out of the country following the Conquest, is older than Robert, and it goes against the Bastard's plan to divide his English and French possessions.
 
I doubt that there is a plausible chance of these two meeting and wedding.

A better marriage would be the one proposed when he was a child, he was betrothed to Margaret, the heiress of Maine, but she died before they could be wed. If she lived long enough to marry Robert and produce an heir, uniting the two dukedoms.
