I think the whole idea behind N is antenna diversity Daniel. Using less antennas means he'll get little or no benefit from the system. Might as well just run with a standard b/g system.
I think antenna placement will also be critical for n. I could be totally wrong here, but my guess is that there are specific distances between antennas that are part of the magic of n. What's he hoping to accomplish?
