I would recommend against a "mis-matched" center, as it will not work! You'll never have a believable, cohesive soundstage, with smooth tonal transitions, and a system that "disappears". Rather you'll always be aware of tonal shifts in the sound, and the fact you are listening to "speakers" and gear, not the soundstage!
I would also recommend against small single woofer/tweeter designs, in favor of dual mid/woof speakers, which will control acoustical reflections from floor to ceiling, and provide often better transient reinforcement, and dynamic impact, dialoge inteligibility, etc.
Alternatives I'd recommed are Polk RM7200 system (???...maybe it's 8000), Infinity TSS1100 system, and little
Atlantic tech or M&K Systems as such.
I used to sell the otherwise very clear and detailed (on axis, that is) Maggie system lacking dyanmics for movies, and not so strong, while off-axis listening is combfiltered for a rolled off sound.
hope this helps...
