My thoughts are this:
First, If you are going to replace the antennas, use three identical replacements. If mis-matched antennas performed better, it would ship that way.
Second, if the stock antennas are not good enough, you are trying to cover too large an area. You should be looking into adding additional access points, not adding bigger antennas.
