I might give this a try especially since I hate having to readjust Lee dies everytime I mount them on my press.
You can try it, the only way to know is to do it. I kind of doubt that it will fix the problem, the biggest problem with lee dies is that the bullet seater floats in the die, and there is no suport on the case neck when seating bullets. On the rubber on the bottom of the rings, some experts say that this system works better, and they use them on their high end dies, stating that the die alings itself, and decreases runout. Some will use o-rings under their lock rings to mimic the lee lock rings. It is one of them things you just have to try and see. Here is an article on the subject.
