If you do a folder / file level comparison between your copy of infocus and the 9 MSMW themes you should be able to decide which is the closest match. I'm not sure what tool you might use to do the comparison. I use a commercial product called DiffDog from Altova.
I would love to be able to tell you which of the 9 MSMW GPL themes is a close match for inFocus and Awake but, disappointingly, due to the nature of the ThemeForest proprietary legal terms I can't even touch a copy of Awake and inFocus AND maintain an open source repository for the 9 GPL MSMW themes. Neither can any contributors to the BackStop themes.
NOTE: My interpretation of Themeforest terms is personal. I am not a lawyer. If you want a proper legal opinion of the Envato terms...please consult a lawyer (sorry for the disclaimer...just playing it safe :-).
If you do the folder comparison and decide one of the 9 MSMW themes is a close match for inFocus and / or Awake, could you post that on this forum for others.
I would love to have had a simple migration option for Awake and inFocus clients but, it is not within my power unfortunately.
