The steering sector shaft inside the case of the chuck must ride on some sort of bearing, right? This makes 2 points of support if the add on kit is added. I'd think that it would be unlikely to flex enough to cause damage. The oil seal may deform under some stress, but if everything is in good condition, I see no problem. I didn't understand the reasoning regarding the shortcut in steering box supports a few posts back. Maybe the HEMI mounts share the same space? I agree with Steve, the strengthening of the steering mounts should be the lions share of gains of K member welding.
