How about with Barry currently struggling to find a balance between his regular life & heroic duties, why not have the following?
Barry remains a member of the JLA and bases himself in Central City working CCPD and staying on top of the craziness.
Wally bases himself in Keystone, Bart & Max live together again, Jesse back in charge of her business with all working together to handle everything that arises around the globe.
(The Rogues for these characters is already excellent. Savitar, The Rival, Inertia, Kilg%re, Razor, Folded Man etc.)
Everyone has a job to do, but can also join forces should the situation call for it.
