I think players should take the offseason in December to help promote badminton instead of training (even partially). It should be like helping out with a charity or something like that. Seeing NBA players working with children teaching them to read helps promote the sport in a big way. The effect snowballs, plus they are helping out with a charity. The event should be BWF sponsored and international.
Great ideas. If everyone willing to donate a bit effort here and there, the community can only be improved in no time.
