Wade would help but not as much as a player of his stature should. Obviously there's the health issue. But even when playing he doesn't space the floor with shooting while off the ball though he was a great cutter when playing with Bron before. He's no longer a great defender and he's not big enough to really guard 3s (ie KD) either. Ideally he'd be better as a bench scorer simply because I don't know if he's an improvement over JR Smith in the starting lineup simply because his skills are redundant and they need Smith's shooting out there next to Kyrie and Bron. Obviously Wade is better than Smith but its a weird fit.
