What the Championship could do is continue like normal during the International breaks. This will mean a less overcrowded football calendar where teams will play three games per week for a good portion of the season.
That would mean following what Spain does. During International breaks, La Liga teams don't play (like the Premiership doesn't) but the second division as well as the lower divisions continue like normal. The Segunda División (Second division) in Spain has 22 teams in the league (2 less than the Championship) but by continuing to play during the International break, they only have to play a couple of mid-week matches per season whilst the season runs for a little longer. It usually finishes in mid to late July.
