How to reverse the subdivide effect?

Am familiar with displacements and am usually happy with the subdivide but I'm trying for a special effect.

Just so you can picture it - three rectangles - one centered, the two on the ends at a 45 degree angle, make one side of each the displacement face so the three are side by side, high-light the faces and hit subdivide. Result = a curve that warps out from the straight edge. so it would look something like C| < imagine the C connects to the ends of the straight line.

Is there anyway you can get it so the C faces the opposite direction when the subdivide process happens?
