Will a lip lift benefit me? (photos)

I am 59 and am considering a lip lift. My nose to upper lip is about 2.1mm, and my lower lip to the chin is about 3.1mm. Am I a good candidate for a lip lift? How many mm should I have it removed? While doing the LL, can I also change the cupid's bow shape? Attached 1) one with smile but keep lip closed, 2) the other one smile but have lips open, 3) no smile Thanks!
