Not really. Will is not in any circumstance to return to the films. Reasons why are clearly put within the films: he can't abandon his duty without turning into a creature like Davy Jones was...and as Will looks nothing fish-like in the AWE epilogue(which takes place long after the four films), he didn't abandon his duty.

So unless if for some reason, they found a way to bring Will back(highly unlikely)...any return of Will(or Elizabeth) is a fan's wish, nothing more.
