There's plenty of options. They could gut campaign to 10% to make "space" for halving Light/Basic and Value/Classic. They could also introduce 30% and 70% earnings like JAL has on the AY+ chart.

I hope they just keep the current value, except for increasing flexible PE to 150% (equal to flexible Y) but it's ostensibly wishful thinking. (Not that I ever plan to fly flexible PE, it's just for consistency.)
