Changing one thing to fix a different issue does not make sense to me. I had a similar problem and found an old jack stand with a round post. The light weight sheet metal ones, not the newer cast style. Anyway, the trailer jack fit perfectly in the base of the jack stand. Took off the foot, drilled a hole and now I have a wider base for the trailer jack and it doesn't have to extend as much, making it more stable.
