Tom you may have a point when it comes to the scabbard of the middle one, being possibly Malay.   
 
However I would still say that the piece is Moro, and the missing ganga may be hidden since this is done sometimes and not well lit.   
 
I also disagree with you on the development of the cheeks being a recent development (if I understand you) since full cheeks also go with older pieces on say mid-1800s without the tail flare.
