Currently as it stands right now with the token system, if you are clearing the content in a relative quickly manner, you will get all of the gear you want. Of course this varies based on what your "best in slot" is, and actual drops from clearing every week. All your system does is allow for people who are coming into the season later, and give them a sort of pick-me up. But in reality, we already have that with the 24-man raids. It comes out at the halfway point between raiding seasons, and always has been a way to get extra gear that is of equal ilvl to the current, no-upgraded token gear. I see nothing wrong with the current system in place and think that your idea would be nothing more than a waste of resources to implement.
