Finding a heavier tripod is usually easy. Lots of ways to get more weight.
Here are ways to make a light tripod work for you.
A: Keep it lower to the ground. Bending moment (engineering speak for wobble) goes up with the square of the length. And the upper seconds of the tripod are heavier and stiffer. Using the tripod collapsed may reduce wobble by a factor of 20.
B: Take a piece of fabric and sew a triangle. Put ties on the corners. Depending on your tripod the leg locks may keep these from sliding, or you may need to glue hooks onto the tripod. You may be able to leave this in place all the time, which as the side benefit of having a shelf to put lens caps, the other lens, the iphone that you are using for live view, running Arsenal.
C: Don't use the elevator to raise the camera.
D: Put the tripod over your pack, and rest the bottom of the elevator on your pack, or splay the legs enough that the bottom of the elevator is on the ground. Stumps and rocks can be used this way too. Sometimes it may mean you use an inch or two of elevator to match the tripod to the fire hydrant.
E: Use a lighter camera. It's much easier to keep a 6 oz camera still than a 8 pound view camera.
F: Take lots of shots and hope that one is during a lull in the wind. Memory is cheap.
G: Faster shutter speed to get crisp detail, even it means you crank up the ISO. Slower shutter speed to get rid of the iso noise. Then you have an interesting compositing challenge. (Use the faster one to make an unsharp mask that you use on the better colour one.)
H: Set your with unequal leg lengths. If you can get a stable position with one leg 10% longer and one 20% longer than the third, you may avoid resonances and the wobble will damp out faster.
I: Use mirror lock up. Lot of that vibration is started by that mirror going CLUNK out of the way. Lock it up first, or if your camera as a feature put a delay in raising the mirror and taking the shot.
