Capturing Non-Sysprep Image With ZTIBackup.wsf

I would like to backup the user computer to a WIM before formating and installing Win 7.  USMT is great and stuff but it's not going to catch the fringe items without a bunch of extra planning.  I've added the MDT Toolkit package to ConfigMgr to access ZTIBackup.wsf.  It appears a .WSF can't be executed?  I could probobally just create a Run Command task to execute ImageX but the ZTIBackup is already built.
