ArcHydro: Python Script: Centroidal Flow Path

I'm looking for assistance from the ESRI community to write a python script that will calculate the Centroidal Flow Path of based on the Longest Flow Paths and Drainage Area Centroid. I need to project a line at right angles to the Longest Flow Path split the Longest Flow Paths, remove the segment upstream of the Drainage Area Centroid and report the remaining segments as the Centroidal Flow Paths for each Watershed. I've attached a image to better explain what I'm trying to accomplish. The reason for wanting to script this is that I would like to embed this into my current ArcGIS Model that I've developed using ModelBuilder.
