Yes that sounds like it would be a good option to have in a trainer for the game.
I for one really hope that you can achieve 100% readiness without the co-op missions... I hate the thought of having to rely on others to achieve my goals in this game. That means I would have to take on the extra effort of finding people to play those missions... plus I would have to play without the trainer options as those would most certainly get you banned from playing in the multi-player scenarios at a bare minimum. I love my trainers!
