Looking for a roster set

[Syxx34]

Im looking for a smaller roster set then the normal MLB roster set. The one that has 2 Triple A Leagues, 3 Double A leagues is to big for an online league with what I want to do. I am looking for roster set like this:

Major League
Triple A League (30 teams with 1 team belong to 1 MLB Team)
Double A League (30 teams with 1 team belong to 1 MLB Team)
Single A League (30 teams with 1 team belong to 1 MLB Team)
Short A Season League (30 teams with 1 team belong to 1 MLB Team)
Rookie League (30 teams with 1 team belong to 1 MLB Team)

Reason why I want it is because it makes less files and makes it easier to upload on me and everyone else and saves space since I want to add 2 or 3 feeder leagues: NCAA (real teams - fictional players), High Scool (Completly Fictional), and possible an Internation League (Completely Fictional)

Any roster set out there with it set up like this?
