I'd go with something else for towing. Did a lot of research on the Odysseys before buying an '05 model last summer, and one of the big reasons we went with the newer body style was the improved transmission. The older ones seem to suffer a combination of poor design and very high temps, especially when towing even light trailers. Frequent transmission fluid flushes, aftermarket transmission coolers, and transmission temperature gauges are prerequisites for towing according to the OdyClub forum. I would only think that a supercharger would add more heat to the equation, which is the opposite of the way you want to go.
I towed a 3500 lb. cherry picker that I rented at Home Depot this weekend behind my '94 Chevy K1500 (1/2 ton short bed with a 350, proper receiver hitch, aftermarket transmission cooler, and a tow rating somewhere around 6,000 lbs). The cherry picker/trailer combo did not have any brakes, and I would definitely want some electric brakes if I was going to tow that kind of load for any distance. After this weekend's towing experience, I also subscribe to the "go for overkill in a tow vehicle" philosophy. I'd rather tow with something that has some significant headroom built-in, as opposed to something that's at the ragged edge of its limits.
