Enable Z values on an existing Featureclass

I am trying to write a python script to take an existing featureclass that does not support Z or M values and enable enable them.  I know that this cannot be done on an existing featureclass (why, I'm not sure!) so I wrote my script to create a new featureclass using the original as a template, then copy over all existing data, delete the original featureclass, then rename the new one to the original name.  Sounds great, but the issue now is that if you create a featureclass using a featureclass that does not support Z values, the newly created one will also not support Z values, even is explicitly set to 'ENABLED' in the code.  Does anyone know how this can be done, or if there is any errors in my code:

import arcpy
from arcpy import env
import os
import datetime
env.workspace = "database connections\BASE.sde\BASE.BASE.Test"
Path = r"database connections\BASE.sde\BASE.BASE.Test\BASE.BASE."
arcpy.env.overwriteOutput = True

#Prompt user for FC to copy
FC_Copy = raw_input("Enter Featureclass name to copy: ")
#Copy original FC to a new '_Temp' FC
arcpy.CreateFeatureclass_management(env.workspace, FC_Copy+"_Temp", "POLYLINE", Path + FC_Copy, "ENABLED", "ENABLED")
print "Table " + FC_Copy + "_Temp added..."
#Copy over existing data-how to ensure ObjectID's don't change?
arcpy.Copy_management(Path + FC_Copy, Path + FC_Copy + "_Temp")
print "Copied original records to " + FC_Copy + "_Temp..."
#Delete original FC
FC = Path + FC_Copy
print "Original Table, " + FC + ", has been deleted..."
#Rename copied FC to original name
arcpy.Rename_management(Path + FC_Copy + "_Temp", FC_Copy)
print "New Featureclass, " + FC_Copy + "_Temp, renamed to " + FC_Copy + ". Z-enabling script is completed successfully"
