Revision rhinoplasty question - adding cartilage?

I just saw a surgeon and he told me that my bridge is too thin (I agree and I hate it) and my tip is bulbous and it lacks support. He said he will widen my bridge with septum cartilage and add cartilage to my tip for support and make it thinner. Does this sound reasonable? I don't want to regret my choice again. I hate my nose now, I was prettier before surgery and I just want to have my face back! So are these techniques common with less risk?
