The thing is that some might feel this sort of hampers one of the traits that fullrange enthusiasts usually crave, and that's imaging. One suggestion that may help is to also horn load the front of the driver, like the eight π, so that angular coverage of the midrange is limited to reduce reflections from the floor and walls.

I'd probably keep compression down to 1-to-1, hoping to retain high frequency performance. This would result in light horn loading, with the main advantage sought being that of pattern control, and my guess is it would also help keep the response balanced. Might be something to look at for the single driver enthusiasts.
