You don't want this, trust me on that. That would be a ****ing dumpster fire of epic proportions. If it ever came to pass the states where you really need it would neuter the shit out of it so badly it wouldn't help, and we'd all be saddled with extra BS from the feds. Keep the feds out of it! The pro RKBA states need to start offering enhanced permits alongside existing ones that will increase reciprocity. I think there is already at least one state doing this or talking about it. This gives permit holders extra reciprocity without screwing people out of their rights- people are still free to apply to and receive the "lower" permit. It would be trivially easy for a state like Utah to develop an enhanced permit that has requirements that are met in nearly all the shall issue states, and they could probably charge $125 for it and people would jump all over that in a heartbeat.
That said, I do think that FOPA needs to be reformed and enhanced so it is less ambiguous and more protective of citizens.
