I do not know what that clever marketing gimmick would be tho.
Saturate the public with short & regular advertisements in every media which feature a bunch of very cool looking young people saying over and over and over "Wanna know something? Just Bing it!". That's where I'd start ~ they gotta get people to think of Bing as an alternative. Right now, they don't think of it at all.
