A patron saint for the United Kingdom?

The Independent reports that Dr Ian Bradley from the University of St Andrews has proposed that St Aidan become patron saint of the United Kingdom. As someone for whom stories of Aidan, Oswald, Cuthbert and all were the stuff of first school history, I am attracted to this idea; though doubt whether a St Aidan's Day would at first attract even as little attention as St George's Day has until recently.
