Uh, it's 6 hours to Boston, the nearest "port of call" - to say nothing of the chance the player is from California. The fact that you have to deliberately misrepresent the distance by calling it just "a few hours" proves your point is a poor one.
I honestly hope the NFL tries it. As long as it isn't New England moving, I got no skin in the game and I'll enjoy seeing it explode in their faces - and having an AFC East team we can count on to go 3-13 annually.
The Chargers are already demonstrating Goodell's incompetence. Anyone could have told you Los Angeles wasn't a big enough football market to support two new teams. The problem is finding an adequate city for them and potentially the Jaguars (unless London is really on the table). Let's review the potential cities.
San Antonio - Jerry Jones says no
Oklahoma City - Jerry Jones says no, sir
Toronto - the Bills are next door
Montreal - the Patriots and Bills? (Maybe at 1.7 million this is a viable option)
Portland, OR - the Seahawks and 49ers
Vancouver - the Seahawks
Calgary - this could work and it is 1.2 million with a large geographical area currently not served by the NFL. Passion for the sport may be an issue.
St. Louis - give it time, the tombstone is warm
San Diego - give it time, the tombstone is still warm
Omaha - I could see a regional team, a la "New England" doing well in Omaha with Lincoln and Des Moines, Iowa having roughly a million people and a passion for football. It may be too close to Kansas City.
Mexico City - racism and cultural biases and Jerry Jones stop this one dead in its tracks
Birmingham, AL - on the small side but also passionate about football
Chicago 2.0 - another club in Chicago, a major sports city, could work. I'd personally like to see the league move the Giants to the AFC East and this second Chicago team to the NFL North (shuffling the Lions somewhere else).
So my top pick is actually a second Chicago team, moving the Bills to Toronto, and Omaha if we're talking the United States and Canada. If we allow for Mexico, Mexico City is just waiting for a team. London is a better option than any of these if there can be a new conference but otherwise there are too many logistical issues.
