The issue here is the size bag you can take on a plane rather than what's in them. Bear in mind and excuse the flippancy but I don't know of an airline that has reported a hijacking whereby a badminton racquet was used as the weapon of choice.

I think you will be asked to place racquets in the cargo area rather than on the plane so would suggest you pack you bag on this basis. Personally, i would place clothing either side of my racquets to provide as much cushioning as possible. i would also tape my racquets together whilst still in their individual bags to ensure they remain together and therefore will create a stronger package.
