Based on the imaging you did of your profile, I would say it is possible to get that change without osteotomies. However, if you were my patient, I would have to have the option of doing bone work if your profile reduction resulted in an "open roof" deformity during the surgery. This is a situation in which, due to profile reduction, a gap exists between the nasal bones along the bridge.
If you think of the nose like a triangle, then removing the top of it results in a space between the two sides. Osteotomies are done to move the bones together again in the midline, remaking a narrower and shorter triangle.
I would have to examine you and see how long your bones were. Longer bones would increase the likelihood of needing osteotomies. Whether or not an open roof occurs also depends on how thick your bones are to begin with. Men tend to have thicker bones than women, so that is going in your favor.
Your tip position and size look appropriate for your facial structure. You might require a small graft to maintain the tip position. Again, that would depend upon the examination specifically.
Finally, you might also consider a chin implant, as that would strengthen your profile and simultaneously de-emphasize your nose.
