Yep, that's what I'm suggesting. Yes, it will run hotter, and might have slightly more THD (still well below audible, though), but its not like they aren't designed to do it, and provided cooling and power is adequate, won't have a noticeably shorter life. Not to mention the capital outlay is less. Basically, you're just getting your full value from the amp.
Don't get me wrong, your observations are valid. But, if we were really concerned with work, heat, and THD, we should all buy 1000 watt amps, run them at 8 ohms, turn the gains all the way down, and keep the volume at 1/4. This would also get us around 100 watts to each set of mids.
