Fix for plunging septum and harsh Nares when smiling? (Photo)

Hi, I like my nose when I am smiling with my mouth closed or at rest (first pic) but as soon as I talk or smile with my mouth open my septum dips down and my nostrils widen so harshly (in my opinion) that it makes me dislike smiling. What could change this without a full-on nose job? Threads? Botox? I've seen filler used on the nose but im afraid if my tip is lifted, I'll have too much nostril show. Advice is very appreciated, thank you!
