I think your idea has merit. The only thing I would criticize is the timing but even that may be irrelevant.
I say that because there are so many leagues (which I again think there are TOO MANY) that will be impacted by an effort like this. That being said though, I say that it may be irrelevant because some of these same teams will probably end of folding in mid-year which will still cause major disruptions. The bottom line, while well intended, people AND leagues that embark on this type of expansion REALLY NEED TO give more thought to creating these teams.
