To me the main benefit of spherical bearings is not their low friction rotation, but the fact that they will self-align two mounts about 4 feet apart.

However, in the front of both my track cars I have dealt with this by taking advantage of the length and strength of the bar. When the bar doesn't line up with side B, I pull it back and bend the sheet metal with the bar as a lever, and try again. A couple of tries at most will do it. Chances are good that you won't have to repeat this on Side B, but you can easily do that. Once in line, the bar will keep things that way.

A great machinist, now sadly passed away, taught me, when making spherical bearings to hold my front A arms, that the a shaft ought not be free to rotate within the ID of a spherical bearing. You want to be able to clamp the shaft to the spherical bearing. I'm not sure just how you would do that effectively with a sway bar, but it would be worth working on.
