No that won't work, you will still have all the odex files in place and it will casue issues.
Flash the DeOdexEERR, this will properly DeOdex your phone, delete the correct files, and install my theme.. THEN you can use the DeOdexed Back to Stock to remove my Theme and have a Stock DeOdexed ROM.
That makes sense. Glad I asked before doing anything. Thanks...
