I just don't think it's pure laziness.
And if you look at the art, he was often drawn to sort of lool like Logan. And their similar bodytypes was even commented on by Laura in Collision.
And it's not that he looked like Logan's opposite, it's that he was trying to make himself different from Logan completely. It's why he concocted elaborate plans and went to operas and enjoyed fancy suits. Sure, he did seem to enjoy all of those things but he was also working very hard to not be like Logan in terms of personality or looks.
But we always had the idea that Daken was lying to himself. He'd go on beserker rages similar to Wolverine, we would find him just hanging out in seedy bars like Wolverine, he'd get plastered like Wolverine, and this all finally culminates in Wolverines where we discover that he looks exactly like Logan when he lets himself go and he's at his lowest.
So him looking like Logan here is a very important visual so long as Leah has the story move in the direction that Daken is trying to change himself and a way to do that is to model himself on Wolverine. Or he's doing it to lull the others into a false sense of security.
