You'd need to write a script that specifies what files get flashed to where & create your own flashable zip. Or you could swap the files from the tar into an existing CWM flashable I guess; not sure if this will work tho, the script may be specific to those particular files & might not work with different ones (I'm not au fait with these scripts, hence not being sure). I personally wouldn't try this tho, just flash the tar in Odin already.
