I have! Growing up I have wondered what I would look like with a cute perky nose, my sister has one, few of my friends have great noses. Mine is well standard, strong, from God that's for sure.
make over tool is a site that allows you to import your photo and do some adjustments to see if surgery is an option for you. I did a few line removal and reduced the size of my nose as you can see.
I found it interesting the slight change it made, the nose was kind of cute, but would I go that far? if I had a broken nose or breathing issues - sure, but just for cosmetic fun? No, I am fine with my current nose, it fits my face
