Lucci is aleady reserved to Luffy
Califa should be taken either by Nami or Robin. A catfight is a must
Kaku is a hard one. He uses a blade, he kicks and he throws blades too(Wow,it's like a riddle). He also have a long nose.
Blueno/Kumadori/Fukuro are the biggest guys here. They can be best suited for Franky and Chopper.
We've seen Spandam was holding a sword before but it doesn't necessarily mean he's a swordsman. Robin was holding a sword in a one of a colorspread before. Holding a sword sometimes just adds coolness and badass points.
Jabura- Either Zoro or Sanji just because he stands next to Lucci
Hattori should be raped by Chimney and Gonbe, the cat
Spandam's elephant is a good opponent for Yokozuna
