Tried and failed. Going to try morphing. Script to align all the vertices between two. Link: http://www.polycount.com/forum/showpost.php?p=1016735&postcount=2
An another script maybe. Or: http://forums.autodesk.com/t5/modeling/aligning-vertices-in-a-straight-line/td-p/4106016 There is a button called make planar by the way. Or you can scale the verticles on an axis.
