As far as I know there are no morphs included with any character that I know of at least, that does whats in your picture. But to me it looks like it were done with a morph tool, maybe in zbrush as it have some good tools for stuff like that.

The face is as you know made of a mesh which contain facial features build into it, so unless a new face is made to fit the rest of characters body mesh its not that easy to simply replace it as it would require you to rig the character again, that is why I assume that it was done using a morph to smoothing out the facial features and maybe finish it in photoshop/Gimp. Alternatively you might be able to place a sphere (Egg shape) so it covers the face and then parent it to the figure so it stay in place, then use the morph tool to fit is as good as you can. Apply the texture to it and paint out the seams in PS/Gimp if there are any.
