The Wolves barely survived their assault on Alexandria, and the ones who escaped were gunned down by Rick outside the RV. I find it highly unlikely that any pockets of them exist elsewhere, as they didn't have a permanent camp where they lived. While it seems that they were building a walker army, herding the dead back into the trucks at the end of Season 5, they were alos just randomly killing weaker redshirts in Alexandria. Their intentions were totally unknown
thing about what you said now is:
a. The whisperers also dont have a perma home
b. We dont know there arent any more wolves, it couldve just been a few from the pack and the rest stayed behind. We saw that they were all sprawled out and none were rly with each other, just like the camp of Negan's that Rick and the crew attacked. They thought that was it but there were more elsewhere
But all in all, i just thought that looking at the time gap from when the crew encounters negan in the comics to when they encounter the whisperers (2 or 3 years i believe) the remenants of the wolves, assuming the show will also have the time gap, could have definitely completed the zombie army and become whisperers. They can even put a new meaning to the W on their heads that way too. W for Whisperers. And sure their intentions in herding walkers was unclear, but then again, what are anyones intentions but to survive? And if there r any other intentions, they get brought out later when they have been carried out.
