Suggestions Please

Weidest question ever.

I want to create a DB which contains 3 nations. Just those 3 though. I know how to achieve most of it (setting up leagues clubs etc) but it is more for internationals and the likes I only want the 3 nations involved and players from those 3 nations only. Also not having the rest of it like world cup olympics and other inbuilt things in the game.

The idea is to use fm for regen creation, fixture creation etc... I realize it is highly unlikely this is possible but any ideas would be appreciated.

Regards.
