Rob and Jared,
The couplers operate using a magnetized wand to lift the steel ball out of the lock block in the coupler head by magnetic attraction.. Why can't the ball and the wand be magnetized so that you could put the wand below the coupler head and have them repel rather than attract in the same fashion that placing the same poles of two magnets together cause them to repel?
You could with a bit of work get the ball polarized on opposite sides but the first time you brought the magnet near it it would flip over so the attractive side was down.

If you used a steel cylinder it would work but there might be too much friction to work properly.

In larger scales you should be able to make the uncoupler lever lift the ball. It is probably possible in HO scale but might not be worth the effort.
