Extending grafts in revision rhinoplasty

I got rhinoplasty done about 9 months ago. My nose was was very flat, I had flared nostrils and my septum was deviated. During the procedure I got rib grafts placed inside my nose to shape & provide a bridge, but no trimming of the alar. Although it looks better now, I’m not completely satisfied. I expected a higher bridge and a pointy nose tip so that the ala would reduce itself as it’s pulled up by grafts. Can the columellar grafts be extended to get a more higher nose tip ?
