The real issue is to sustain the local stations and, perhaps, to create a new version of NPR at the station level to provide certain portions of station programming.
There's no need to "create a new version of NPR." It still exists, as do a multitude of other program suppliers such as American Public Media. Stations such as WAMU and WBUR already create programming that hundreds of stations carry.
If stations would like to get into the national or regional programming business, all they need is money. The public broadcasting interconnection system would distribute the show for them. They just need to find a new way to pay for it.
If conservatives from Texas or other red states want to originate programming, the system is there for them to do it. But they'd make more money as a podcast or commercial radio program.
