The front is what I'm worried about. More for caster than anything. I don't want squirrley handling at highway speeds.
I think as long as you run front springs that were designed by someone and not something you put together in the back yard you shouldn't have any major issues with handling. You might even get lucky with a DIY set of springs, but I wouldn't expect it.
The push-pull steering is one of the biggest handling factors as it causes bump steer that can be an issue with some rigs. My 85 had 4-1/2 inch Superlift front springs and it handled great with push-pull steering. I drove it multiple times cross country.
