What this will do is create a phenomenon of the reserve percentages in the bigger jets going really junior. What it will end up doing is allowing new hires to flying the large jets for the same pay with worse work rules. See it as kind of a "B" scale of sorts.
Guys like me would avoid reserve on one jet where I could do the same thing for the same pay on a smaller jet. The idea that this would allow everyone to have a choice may look good at first pass, but all it will do after a few bid cycles is push the junior guys towards the jets that have the undersirable reserve system.

If this is in fact a proposal, I would be curious to see what Alaska reserve rules look like and if the proposed rules mirror them.
