This is most likely not going to happen and if it did probably going to end badly: What if nobody showed up for these briefings and press conferences anymore?
I'm sure Trump / Bannon's ideal scenario would be to have only Breitbart report on Whitehouse news, and Trump will communicate through Twitter. They'll also manipulate various data released through official channels to reinforce their reality. This is the first president that has been arguing that the unemployment rate is higher than the official recognized rate (I know there are various measures) while he is in office.
