Well here's the final verdict. I was able to achieve the desired result. Although it's obviously not as good as simply double-tracking, I was able to get good separation between the two tracks. All the sound is no longer dead center. I was able to open up the center for the vocals, leads, etc. I panned the original track hard left, and added all the effects there, in this case reverb and delay. I panned the copy track hard right, nudged it forward 10ms, and left it dry, aside from using an amp simulator. It actually worked out so well that I used the same technique (sans the nudging) on a newer song that I had actually double tracked. It made each side more distinctive, gave me more room in the center for vocals and leads, and gave the overall sound more clarity.
