Sure you can,
Ever take a look at Japanese shiko? That stomp that the sumo guys do? That can be easily modified to be a side kick.
Since no one wants to take a stab at it (I'm surprised since this one is pretty simple, imo) I'll give it a go.
Note: All mechanics herein imply that you're conditioned enough that a) you can store and control breath pressure b) you're conditioned enough that the middle is tied to the limbs.
The mechanics of any dantian based movement can kind of be split into roughly two parts:
You got: a) the "skin/fascia/tissue" whatever it is that weaves the body together into a cohesive unit, and its manipulation
Then b) the manipulation of ground and pressure
For a)
So the "cock" of the side kick, is really a permutation of a "close" movement:
http://americangoju.com/bermuda_karate_ ... ingham.jpgThe above is more a muscular version of what happens, but basically:
Say you pull down on the "front" of the abdomen, anyone that's connected will find that doing this will pull the elbows/knees etc towards the body in an elastic fasion.
There's a variation on this, where if you turn the front of the abdomen only (not the hips!), say, to the left you'll cause the back of the dantian to wind to the right. This stretch pulls the left leg towards the body, storing elastic energy. This storing will also cause a compression to occur in the support/right leg.
The elastic portion can get deeper, but I'm trying to keep it simple.
For b)
As you "cock" the left leg by manipulating the elastic tension, drawing it towards your body, you simultaneously compress your support leg. Assuming you have an abdomen that you've learned to pressurize, you should have what equates to a "bowling ball of pressure" that sits right on top of the support leg.
Now you do two things at once.
You release the stored up elastic tension of the "frame"/"suit"/"connection"
and at the same time, you straighten the support leg. Straightening the support leg will push the pressure of the "bowling ball" out into the other leg. (btw, this is "open," and part of it will involve feeling the crotch open kind of)
If you want to add a bit of "omph" then point the bowling ball 45 degrees downward, slamming it down. (hence the stomp in Shiko)
The combined elastic tension, and the pressure/weight, if aimed properly say at, a person's dead angle/third leg, will generally send them flying.
Boiling it down,
pull on the front of the abdomen to "close,"
push pressure up the back to "open" the body.
This opening/closing of the body is what controls the extremities, and is essentially tied to that middle area.
Adding side to side movement, will induce a winding across opposite hand/foot,
and basically mixing and matching this, plus controlling the pressure of the abdomen and how it flows to the extremities, as well as ground force/weight, will allow you to literally control the limbs with minimal involvement of local musculature.
Once you get it, it feels like you're a bit like a marionette on strings...or maybe a sex toy on strings
Any movement that can occur through this mix-and-match can be done "internally."
While the above sounds complicated, it really isn't. The dantian is still at the heart of what controls the pressure and elastic tensions.
Using the same logic you can do a hook or hip throw as well
(Hook, and this is only one way: push the pressure up the back, this will push the arm up and out (open), then pull down on the front to close the arm, point the ball of pressure downwards at a 45 degree angle to get some downward force to the hook (without actually changing the vector).
