Is it possible to develop a great kick later in "life"?

I'm 37. I've been swimming for 2.5 years. I'm a triathlete and was told for the longest time that kick wasn't important so I didn't do any kick sets and focused primary on my upper body form. I've completely turned my thinking around on kicking and I'd like to develop my kick. I've been told/read that it is difficult to develop a great kick if #1 - you didn't start young and incorporate it #2 - if you developed a stroke like I did and then tried to incorporate good kicking. In others opinions is it possible to develop a strong kick given what I've outlined above? I have a good coach right now and we've started a plan to do lots of kick sets (of different types) and weight my workouts over the next several months towards kick sets and other drills given my next A race isn't until mid-Sept.
