Preliminary concepts: very one of us has a degree of septal deviation, no one human being has the 3 elements (2 bones and 1 cartilage) forming the nasal septum perfectly aligned, with that said not every septal deviation is the cause of the breathing issues, actually it rarely is, majority of breathing issues are due to other causes and the type of congestion you explain point more to a chronic rhinitis; with that said, the indication for a septoplasty in your case is not only questionably but also highly disputable, I'd not accept to add such extra financial cost and complexity to an already very complex and costly type of rhinoplasty. However, should there exist solid evidence of a causal link between your septal deviation and breathing issues, then yes, a septoplasty can and has to be associated to the rhinoplasty in the same surgical episode. Your nose is extremely complex and tricky for an unexperienced surgeon, beware of easy solutions and minimally invasive procedures, your nose gathers a compilation of technical problems of high to very high difficulty, among others the following ones: -boxy and bulbous tip, featuring very large alar cartilages and domes plus strongly verticalized lateral cruras, leading to null nostril support and severe alar rim retraction; this alar ascension produces an unsightly columellar show or exposure which, itself, is not an issue to tackle but a consequence of the poor nostril rim cover over it. -The tip, the shiny reflection marking the peak of it, is overly high and rotated up, close to be "piggy nose", this increases the visibility of the nostrils, also to be treated in an efficient manner. -Atypically very broad dorsum with practically no hump on it, this humpless dorsum narrowing is one of the most difficult and risky maneuvers in rhinoplasty, few surgeons dare to do it but if you master it becomes routine; you can't narrow that brige by creating a saddle nose deformity, that'd be the solution for most surgeons, the bridge level is optimal and can't be lower, so you have to remove few mm of bone (upper part) and cartilage (lower part) from the bridge but not in vertical but in horizontal, between the nasal bones and the osseous septum (upper part) and the triangular cartilages and the cartilagenous septum (lower part). I strongly recommend you consult with 10-20 surgeons until you find 1-2 professionals depicting the aforementioned scenario. Refuse easy proposals, appealing minimalist procedures, tons of blah blah blah and medical pride, etc, stay with the surgeon talking loud and clear about the difficulty of your nose (9/10) and no less than 4-5 hours surgery.
