I don't think there would have been any chance of the Victorians changing the rules of succession.

BUT, if Victoria died whilst giving birth to Edward (and Edward was stillborn), then the younger Victoria would take the throne, and her father could act as regent in the "Second Regency" (the first being the one during George III's madness).

If she still married Frederick, then when she died, Wilhelm II would inherit both thrones.

But I also wonder whether the British Parliament would allow it.
