Default Lower ball joint removal

I am trying to remove the passenger side lower ball joint while leaving the rest of the suspension intact. My theory is to raise the car with a floor jack on the frame, put a jack stand under the lower control arm and then lower the car somewhat. Since the steering knuckle comes off the bottom of the ball joint and the upper control arm can pivot freely, with the help of a pickle fork that steering knuckle should fall off the ball joint. Then I could just unbolt the ball joint (it was already replaced at least once) and bolt in a new one.
Obviously, since I am writing, this hasn't worked yet, but I might just need a bigger hammer.
So does this sound like it should work?

Jack the car up by the lower a-arm, place a jack stand under the frame to rest the car on. Lower the jack, (this leaves the A Arm free hanging) and loosen the nut on the ball joint about 1/8", then whack the side of the knuckle with a hammer, the joint should pop loose. You'll notice the 1/8" gap you raised the nut will be gone when it does.

Next, place the jack back under the A-Arm, jack it up and then remove the nut the rest of the way. Lower the arm slowly will release the spring tension... sounds easy, can be... but sometimes its not.

If the above fails then you'll need to rent you a ball joint removal tool or use a pickle fork.

That's the same process I use but with one small change. I completely remove the nut off the ball joint (not just 1/8") then I put it back on leaving a 1/8" gap. This ensures the nut will come off without spinning the ball once the joint has popped loose.
