That sort of spacing will really interfere with your imaging. Many speaker manufacturers go to great lengths to ensure that the drivers in the speakers are "time corrected" - meaning the soundwaves from each driver in a cabinet will reach your ear at the same time. By having the like-channel speakers set apart by 10 feet, the sound from the inner speakers will reach your ears sooner than the sound from the outer speakers. (How much sooner depends on how close you are sitting, of course.)

If you really want to double up the channels, keep the like-channels side by side.
