The entire commuter pay scale is a joke in its execution. I'm glad more people are asking the question. Pay needs to come up at the bottom and down at the top. To ease the transition just have a track system, track one would be current pay scales track two would be the new hire pay scales. Much higher FO pay but capped CA pay.
The current airline pay structure, across the board, is very anti-union like. There is no "we're all in this together", it's more about the senior guys getting everything and those below them getting the shaft.
