Let me ask this another way... In general, is there any reason a center channel speaker(s) makes a bad choice for surrounds?

in general, rear speakers (esp. bipole/dipole types) are designed to project sound as broadly as possible, the idea being that you're surrounded by sound effects. front and center are typically designed to be more narrowly focused; in the case of a center channel you'd expect the sound to project from the middle of the action. ergo, in the usual case a well-designed dedicated rear speaker would be preferable for rear surround. however, mirages have an atypically broad soundstage--they're very room filling and non-directional, so i'd expect a mirage center would serve just fine as a rear surround.
