Yes it is possible to reduce the nasal bone and undergo septoplasty at the same time for multiple broken noses. It is best to seek out a board certified ENT/ facial plastic surgeon with extensive experience in rhinoplasty and revision rhinoplasty for best functional and cosmetic results. Look for a surgeon who is dedicated a significant portion of their practice to nasal surgery. For many examples, please see the link below to our rhinoplasty photo gallery

I think that you need to be seen in person to determine what your goals are and what realistically can be achieved.
It is very unlikely that you cannot have a septoplasty and nasal bone reduction but that will depend on the severity of your trauma and what was done during previous procedures. Seek an experienced rhinoplasty specialist.
