Occasionally, I am asked to do lip augmentation on lips that are very thin. Some of us call these "chicken lips". I tell these patients that I can improve their lips, but cannot give them the full lips of their dreams.
Some of the more presposterous looking lips out there are when physicians tried to assuage the hurt feelings of the extremely thinned lipped patients.
So, in my opinion you really need to have some lip to work with to get the lips you want.
Incidentally, I agree with you that the balloon lips you describe look silly and unattractive.
