No problem.
"Beaming" is not a bad thing with Quads! All electrostats do that, due to the nature of the drivers.
Like Newbee touched-upon, Quads don't spray "highs" all over the place like a tweeter, so they can be placed next to a side wall.
In fact, 11 feet may probably be too far apart, depending on your listening distance and toe-in. (the five feet from the front wall is a good thing) They're certainly easier to deal-with in a limited width room than other types of speakers.
