Yeah, well worth doing IMO.
Basically, stitch weld where the bracket is spot welded to the chassis leg. It is important to get decent welds around that diagonal stiffener/gusset.
Also weld the chassis leg to bulkhead areas. A piece of sheet metal forming a gusset is probably the neatest and strongest solution.
Further stitch welding can be done around the top of the turrets and along the inner wing to chassis seams, but unless you are gonna do lots of track work or have silly power it's a little uneccessary.
