With some creative scheduling they could probably make this work, and increase their TV revenue at the same time.
Keep the same number of games in the season, but expand the calendar time that the season is played. This would give some (if not all, depending on how they want to do it) teams 2 weeks between games. This has the ability to:
1) Account for extra travel time for overseas games.
2) Give players extra time to recover from the inevitable injuries,
3) If they do it properly, they could have some games every Sunday with teams on alternating schedules. Thus putting games on TV more Sundays and increasing the TV revenue.
Not sure how well this would work, But my point is, they have options to make overseas teams viable.
