Reverse cephalic lateral crura trim?

Though there may be some differences in final appearance, if you provide your preoperative photos to a skilled revision rhinoplasty specialist you will likely be able to have a nose created for you that may not be perfectly similar to your original nose but should look quite similar to the nose you once had.  Incidentally, you are not the only patient who I have seen in consultation with similar requests. 

Ear cartilage is often used to rebuilt lateral tip cartilage that has been over resected during primary rhinoplasty. If done well by an experienced surgeon it should look very natural.

It is tough to say from your description without seeing photos, but in general, it is absolutely possible to widen an over-narrowed tip. You may or may not need actual ear cartilage to replace what was done as many times the tip is narrowed with sutures that can be removed. If you do need cartilage, ear or septum may work but it all depends on what things look like once the nose is opened. I would recommend visiting with a few revision rhinoplasty surgeons for in person evaluations to get a better idea of what is possible. Best of luck
