Revision rhinoplasty for the overdone nose is possible. Cartilage and "soft tissue " can be added to the nose. I like septal cartilage as my first choice and then ear with or without the skin is my second choice.
I agree with your evaluation of your rhinoplasty result; I prefer a stronger more defined nose. An experienced revision surgeon will be able to restore thee integrity of your nose with cartilage grafts, probably taken from your ear.
The short answer to your question is yes, specific corrections can be made. In your particular case eight months would be too early to proceed. First of all you're still going through psychological adjustment. Second, the nose needs to totally heal before revisional surgery is embarked upon.
