Neat idea.  

Along those lines, why not a deployable weighted keel?    Get a long, light
tube along the keel (perhaps inside a channel which would have the side
effect of stiffening the hull longitudinally) that is hinged at one end and 
with a heavy, compact weight at the other (depleted uranium, anyone?).
The weight and tube could be teardrop shaped for minimum drag 
when deployed.  If the weight is blade-like, it would provide dynamic
damping to rolling moments as well.

When the paddler is in the water, s/he releases the tube, which swings 
down and locks into place.  Leaving it down would provide stability 
after re-entry.  If the lock yields a bit, it would handle impact, like 
rudder blades and skeg.  

There's a definite downside: seaweed. And currents.  And shallow water.
