I suspect that either introducing groups of players or just a single one will work. Whether it works or not is situational in any respect.
These are the days when I miss the old magazines (Dragon, White Dwarf, etc.) when they supported more than just the publisher's games. Unfortunately, the times have changed a publishing a physical magazine is a cost that is tough to bear. That's not to say that it couldn't be done on the web. But there would still be the two big problems of time and money.
