Let the clubs who don't want to play BCD skip next season and go into hibernation until July 2021 to survive, but on the condition they accept that they will likely be playing at a lower level when they return. Those who do want to play next season can be moved up a division if need be. If we've got 80 clubs who want to carry on, let's have 4 divisions of 20 for 2020/21.
For the rest, being relegated would be better than going bust.
