A single morphed image as you've shown here can only reveal so much. I assume, though, that it's primarily the fullness of the nasal tip that you're bothered by. Depending on skin thickness, a little greater definition of the tip is probably possible than what's shown here. Also, blending the nostrils with the tip a little better (such as with lateral crural struts) might help.
As for the rest of the face and its lack of structure, as you describe it, there are a few options. But first, I would not recommend chin or cheek implants for this face shape. They would likely make a full face seem even fuller. One interesting option would be to consider so-called "facial slimming" with Botox. In this procedure, Botox is injected in moderately high doses to induce atrophy of the masseter muscles at the angles of the jaw. This can help with very square faces, but it requires quite a few sessions early on. It's an uncommon option, but can have really surprising results.
All the best,
