I would think that a pair of mmgs + pair of 12" powered subs would go as loud and clear as needed if teh crossover is done in a manner that offloads most of teh bass below 50-60 hz or so to the subs.
Do you know if that is how you have yours setup? Either the Peachtree or subs would have provide the crossover needed otherwise you would have to use an external one.
If you like the Maggie sound but just need more volume and impact I would check that first in any case. Switching to higher efficiency main speakers (Maggies are NOT efficient at all) might help but still not be the final solution. In msot any any case, in a large room, with a 3K max budget , letting the subs carry the bass load will put you in teh best place possible. The same crossover solution would work with any mains but the settings to blend in well will be different with different main speakers.
