Is it realistic to believe there's hope for getting rid of this massive polly beak of mine?

I made a computer morph of your nose, and an animation of the morph, to show the changes that are possible for your nose in truly expert hands.I elevated the tip and reduced the height of the bridge, lowering the "pollybeak."Have you had surgery before? Usually, we use the term "pollybeak" to describe a complication from previous surgery. Many people, however, have a natural prominence in the lower part of the bridge, above the tip, where yours is.
You should understand that the changes I demonstrated in the morph require advanced techniques, techniques that most plastic surgeons cannot handle.  Be sure to read the section in the "Learn more" link on how to stay out of trouble while searching for a rhinoplasty surgeon, and how to tell whether your previous surgeon should be performing your revision. You should only have surgery if you are able to make yourself very confident in your surgeon's skills. Read that page very carefully. Most plastic surgeons are quite poor at this operation, and I believe my advice will go a long way toward keeping you safe.
I'd love to hear what you think of the morph. Did it seem to address your main concerns?
Your nose is also a good example of why computer imaging is mandatory in rhinoplasty. You need to know exactly what the surgeon is planning to accomplish -- what features he thinks he can change, and by how much he thinks he can change them. When you see his goals, you'll know whether he has an eye for an attractive nose, and whether he shares your opinion of what constitutes an attractive nose. You'll also know whether the changes he proposes are enough to be meaningful to you, and whether he understands your wishes enough to address all of your priorities. But remember, you're not hiring him for his skills with the computer. The doctor must then show you his before and after photos to prove that he can actually accomplish what he draws on the computer.
In your case in particular, you need to find a surgeon who understands all of the issues I mentioned, and how they fit together, and who can actually accomplish them in surgery. 

It is possible to correct the polybeak and improve the appearance of your nose with or without grafting. That depends upon how much height is needed to your tip complex whether a graft is needed or not. A graft can add support or elevate the tip of the nose depending upon its placement which may or may not be necessary. If the polybeak is the result of previous surgery, then less surgery may be required. Poly beaks in general are caused by an overly high septal cartilage, heavy weighted skin with tip ptosis or drooping tip and sometimes scar tissue in heavy or thick skin. These are the factors that can contribute to the success of the procedure. I would see a rhinoplasty expert in your area.

It's not unusual to have what you have, and it's not unrealistic to be considering rhinoplasty surgery, as this is the only solution in my experience for this condition.  Be sure to discuss your goals and concerns with your board certified plastic surgeon and consider the pros and the cons. Be certain your surgeon is properly certified.  I've attached a link where you can start your search.
