It would require establishing some type of entity that would provide officials to college football. I have no idea how that could be done considering that few, if any, conferences would agree to give up their resident officials.
I do know that the current situation is untenable for fairness in inter-conference play. It's come down to, "You have the home field advantage but we are bringing our referees".
Anyone who believes officials are unbiased is naive. There are rules like off sides that are clear and typically enforced appropriately; however, calls like pass interference, holding and targeting have become far too subjective, and are called at the most inopportune of times in the game.
These young men invest too much time and effort to be cheated out of the correct call.
