As a fan, I'd like it. I'd be interested in seeing how players from one fronton would do in the other, and how they would do with various new partners. A month at a time, maybe twice a year, would probably be about right. Maybe four early gamers and four late gamers from each fronton could make the move. As a bettor, I kinda like leaning on statistics for part of my selection process, so switching players between the big two would probably hurt me in that regard, but I'd still like to see it happen.
