Suhiir,
I'd say do it for yourself first. I have been working on the #12 OOB (USA) since version 1.

I have always done mine without changing the original units but, with every upgraded version the slots have gotten less and less.
I am currently going to work on a new version which focuses on more modern time lines (say about 1970 and later). This will open up more slots but, will make it totally unuseable as an official OOB.
I worked on a USMC version before but, every time I got going on it a new version was released and I would have to work on my USA mod.
I have done it for myself and my enjoyment first. If I have had anybody like or dislike it I wouldn't really know but, some things (changes and ideas) have made it into the offical OOB (Great work Don and Andy, USA is very good, just wish there were more unit and weapon slots).
So have fun and I look forward to seeing your work.
PS -- I always thought the USMC OOB was very lacking also.
