dboyce,
In the case of track installation there is virtually no wind noise because the crossbars are not over the sunroof either, they are positioned further back.
It is even easier to remove the locking Railrider towers and crossbars. Simply unlock the locks, flip up the lever, and slide the railriders off the tracks.
I have investigated this option prior to installing Yakima tracks on my MDX. Although theoretically it is possible to install the type of rack you are referring to, currently nobody makes them to fit the MDX. The closest thing that I found is the "side rail" rack from Honda Odyssey. Even though it is the correct size to fit the MDX, unfortunately, the mounting points are in different locations then the mounting studs on the MDX, so the rack would not fit the MDX roof channels without heavy modification (welding in new mounting studs).
