I MAY be able to knock up a simple manager style program to choose the 3 Division 2 teams if my programming skills come back to me
Don't know about editing the exe to include the team names though. The one problem with that would be having to have a different exe, for each possible combination of 3 teams from 10. For those who can't work it out theres 720 possible combinations!
I think the best thing to do, would to include 3 teams form Division One of the County Championship who aren't in Division One of the National League (Lancashire, Nottinghamshire and Warwickshire, I think) for the main 12 teams, to take part in the "World Cup" style tournament, and then have all the rest replacing the special teams, so that they can take part in the knockout tournament. There is however, only 6 special teams that play in the knockout tournament so Scotland may have to miss out after all
Although saying that, being from Lancashire, I wouldn't mind Yorkshire being taken out of the game
