No, no and no. Hisagi wanted Hikone to listen to him, but when he gets ripped to shreds by casual swings of Hikone's sword, it's clear the power gap between them is huge. Zaraki was only interested in him because his Bankai represents everything Zaraki has ever wanted, a person for him to cut down and kill endlessly. He's the sparring partner Zaraki always wanted but could never get. Zaraki gets interested in people all the time, look at Grimmjow. Despite them being far far apart power wise, Grimmjow's ruthless personality and way of fighting was enough to get Zaraki interested.
As has been said my other people already, you clearly don't understand what a NLF actually is.
