I don't think it would change anything. You'd just have 1,000 hour cfi's or 1,500 hour cfi's rushing to cheap pay in hopes of moving on.
It doesn't matter what their total time is when they start. Labor is going to be cheap as long as there is a steady supply of it.
The good news is that regionals are having a harder and harder time finding pilots. They've pretty much lowered the mins down to a CMEL license, so all that's left to do is increase pay.
Simple supply and demand.
