Nope...
I'd say some of us question if you know what you're doing, but we're too polite to say so.
The OTT (over the top) steering is designed for lifted rigs - it moves the drag link connection point up over the springs in an attempt to reduce bump steer, which is why it won't be ideal for a sprung under vehicle, it uses conventional steering ends, so I don't see it allowing any more articulation that the stock system - it's not designed to, the sole purpose is the reduction of bump steer.
If you're running spring under, you should be able to reuse the factory steering arms, but if the linkage isn't man enough then you'll just have to "re-engineer" it - I don't see it as being that complex, assuming you know what you're about.
To achieve what you have in mind you're either paying someone top dollar to do the fab work, or you have top notch fab skills yourself, either way I'd expect either you or the person doing the work to be able to put together a steering system that mounts to the knuckles using the original arms fitted with some sort of high angular displacement joint that won't bind.
