So to try and address the issue of farm teams you want to completely overhaul the system? Not feasible.
In addition, this idea will mean that there will be no training of youngsters in this game as all the training of rookies are being done on this seperate server.
In addition, it provides a HUGE advantage to the people that have the spare time to run two teams as these people will learn a lot more from the game, and also know the skills of lots and lots of the rookies and will know the skills of these players that may end up on other teams which is unfair.
In addition, it will completely ruin this game because suddenly training will not be a challenge at all because winning games is not going to matter at all, it is just going to be about training great players for the main game.
In conclusion, the idea will never be implemented as it will ruin the game that so many love.
