Can Adding a SuperCharger to an Expedition Increase Towing Capacity at all?

Sure will, especially if you go with a whipple (screw-type) supercharger. They make full boost off idle -- so you'll see huge low-end torque (that's pretty flat all the way across the power band) and much better hp under the curve. They are also pretty simple to install vs. a turbo or even centrif. (vortech/paxton) style s/c.
However, you will need to get it tuned on a dyno, along with bigger injectors, match maf, etc to keep the setup safe. Having had a vortech on one mustang and a whipple on another in the past -- the whipple is just a better s/c for around town driving or in your case towing - as the vortech builds boost with rpm. You should easily see a 100hp,120ft/lb gain with a very conservative tune and ~6psi.
