Yeah that will work, as long as the larger gravel is on top. All smaller sizes go lower in a tank, over time. I did that with some Eco complete once and it looked fine.
BTW, do you have pretty hard water? SMS will most likely radically lower the pH/KH/GH. Which is good if you have very hard water. If you don't, something more inert like Turface Pro League, or Flourite might be the way to go.
