I doubt it, they're all old farts :| it would compeltely destroy the notion of WB, Garp and Sengoku being old, weakened men from the previous era and then having some group of even older people being stronger than everyone else in the new era -_-'
No doubt at a certain point they were ferocious fighters, I even suspect one of them to wield Shodai or Nidai Kitetsu, but they're old and surely got a lot weaker.
