I think almost everyone wants it to be every 4 years. In my opinion it should be held the Summer of the Euro. It would make the quality of play better in both the Gold Cup and the Copa America since they would not conflict anymore and teams like Mexico and USA could send their best to both. But it is all a pipe dream due to greed. The CONCACAF will not let that happen. They love having two tournaments for twice the revenue. As for inviting teams I am all for it but once again I don't think that will happen either.
