BoB- On my list of things I want to do is this: I do what probably most people do, is to run all my speakers small, and crossover over everything (plus the LFE channel) to my sub.

Someday, and now I know you're the expert that I could get some help from, is to buy another sub, and run just the mains full range, using the sub's crossover to split out the bass. I guess it's still a partial solution, because I'd still be running the center, and surrounds and rear(s) small. Well, I'm still into the "figuring out" process in terms of that...
