Is it possible to get my nose similar to the picture posted? (Photos)

The major issue with your nose now compared to the pictures is that you have much more slope and an over projecting tip. You should go over your goals with your surgeon and hopefully depending on your conversation have confidence that your goals can be achieved.  Revision rhinoplasty is more difficult and it makes experience in revisions makes a great deal of difference.

Thanks for your thoughtful post and photos. Your current nasal photos indicate that your nose length has decreased and your tip is overprotected and over-rotated in profile. This may be why you feel that it looks too 'piggish'. To achieve your ideal "Bella Thorne" nose, you will need to consider a revision to de-project and lengthen your nose, while improving your profile to be more consistent with your expected goals. Frankly, these are challenging revision concerns, and proper correction requires an experienced and skilled rhinoplasty specialist. It seems reasonable to discuss your concerns with your surgeon, but I would consider other expert opinions from trusted and experienced rhinoplasty experts before you proceed. Best wishes. 

Revision rhinoplasty is more difficult than a primary rhinoplasty, due to the fact that there's been previous alterations the normal anatomy and scar tissue formation. It is very important to have realistic expectations about what can and cannot be accomplished with the procedure. The small dorsal hump it's present can be shaved down, and the hanging columella reduced. And in-person examination is going be required to make a determination about how much de-rotation can be accomplished with the procedure. Consider a chin implant to augment the chin forward to help  with facial balance and proportions, especially with respect to the projection of the nose from the side profile.
