Having installed a disc brake conversion on a dropped axle, I would say that it is doubtful that the axle drop would affect the steering stops.
The disc brake conversion can cause serious problems with the stops- the aftermarket caliper mounting plate can hit the factory stops, limiting your steering considerably. My conversion did exactly that.
Check those cadmium mounting plates- I'll bet they are hitting the steering stop on the axle (they aren't supposed to touch it). If you remove material from the mounting plates to provide clearance for the stop (the little steel angle piece that is held by the kingpin retaining bolt), you might find that the caliper hose fitting becomes your new steering stop (and that's a lot worse than a large turning radius). Then you'll have to remedy that. It's a real bummer. I am still sorting mine out. It has nothing to do with the drop though...
Shortening the steering arms (if that is what you are referring to that you had welded) is a bad idea.
