The problem isn't so much that you won't be able to steer at a stand still.
The problem, in my eyes, is bump steer and brake steer. The factory system has the draglink relatively close to the same length as the front half of the spring and they're at virtually the same angle. That's the idea to minimize bump steer in a push/pull application, for the draglink to be the same length as the front half of the spring and at the same angle.
By going to 52's and a shorter draglink, you make the front half of the spring longer and the draglink shorter which means lots of bump steer. Not only does that mean lots of bump steer but also brake steer, when you hit the brakes and the front of the truck dives, it will steer itself to the right.
Steering that doesn't work when you're twisted up offroad is annoying but not dangerous. Soft springs (the point of the 52's, right?) plus a steering system with lots of bump steer is not safe in my opinion. My .02
