might as well jump
Here's a progression that will have you landing (and floating) with stability and confidence:
1 - practice w/o your board on a flat piece of turf. start by lifting up your front foot and jumping off your rear foot (mimics riding up the angle of the kicker). bring both feet up underneath you while in the air, and then land on both feet simultaneously while absorbing the touchdown with your legs.
the quieter your landing, the better the absorbing. (try it 6-8 times, or until you can do it 5 times in a row)
2 - do the same exercise with the board on (when you can do 5 in a row really well go to step 3)
3 - traverse across a gentle slope and make the same move (when you can do 5 in a row really well, go to step 4)
4 - ride straight down the gentle slope and make the same move (when you can do 5 in a row really well, go to step 5)
5 - choose a small bump of snow, or a roller and make your new move off of the bump/roller (this gives you more air time and a sense of float before the landing) (when you can do 5 in a row really well, go to step 6)*
6 - start with a small/beginner kicker in the park and practice your new move (as you consistently land the jumps, start to add more speed, and air time)*
7 - gradually work you way up to bigger and bigger kickers
*as you start to get more air and begin landing on the downside of bumps or jumps, you'll have to tweak the flatland exercises to have the front foot landing slightly first (really both feet will still land together on the downslope of the jump, but inorder to mimic the effect of the downslope you'd need to land front foot slightly first on flat ground)
Let me know if you have any questions.
