The best way to rebuild some kind of RW media system would be simply to gather all the announcements coming from the Trump administration, broadcast them, flesh them out, and modify or correct them (very carefully and respectfully) when that's necessary.
In that way the media enters into a healthy feedback relation with power while everyone can listen in and develop various feedback relations to the media, with that feedback finding its way back to the center.
The starting point of media reporting is what the government tells you, records or reports, but it doesn't end there. Cultivating sources inside the government, without romanticizing "whistleblowers," can be done is less adversarial ways, with criticism drawing on contrary
government reports, lawsuits brought against the government, etc. Media operatives would then no longer self-aggrandizingly claim to usurp the investigatory and prosecutorial functions of government. There must be media figures sympathetic to Trump and untainted by equivocation
over systematic liars like Owens and Carlson who could initiate such a project. You could even include footnotes with your reporting.
A precondition of this, though--or maybe a concurrent condition--might be suing the mass of podcasters, etc., into bankruptcy, a project that would be valuable in its own right and would itself, almost inevitably, yield a new media.
