Here are my thoughts.

-I feel that shaft bearings are superior to cone bearings. If you look at surface area it just makes sense.
-Bracing is really about load distribution and keeping loads under control.
-Additional mounting bolts provide more clamping force and increase mounting surface area.

Here is a start:
Use shaft bearings in place of the cone bearings at both ends of the idler arm. Not only should shaft bearings last much longer but they could be replaced. Shaft bearings by design should help to distribute and spread out the load.

The actual arm between the bearings should attach as close to the middle of the bearings as possible to reduce leverage and stress load.

Replace the bar that mounts to our frame with a mounting plate that covers more surface area. In addition to our existing mounting holes this plate could be held in-place by two additional bolts. Each bolt would be located a few inches to either side of our existing mounting bolts. This plate would need to include studs for our existing mounting holes as we cant run bolts though the shaft bearing... obviously.

This should give a pretty good idea of what im talking about:
