The first sidewall reflection will have to be treated (diffused or absorbed), but that six feet of open space avaiable behind the MG-12's makes me optimistic. I have used dipoles fairly close to side walls (6" or so) with good results. Sure you'd like a bit more space, but you would with a conventional speaker as well. On the other hand, with the Maggies you'd place the tweeter sections to the inside, so they'd be relatively far from the side walls (compared to a conventional speaker's tweeter).
Remember, a dipole's figure-8 radiation pattern is going to give it less sidewall interaction than a monopole speaker would have. In a less-than-ideal situation as long as you can get plenty of space behind a dipole, it will usually be less room-sensitive than a conventional speaker.
A tall fake plant along either side wall, a couple of feet in front of the speakers, would probably adequately diffuse that first sidewall reflection. You might have to shop a bit for a plant that fits the space well.
