I would agree with your analysis regarding the Bobby Baker scandal and LBJ. jerome Corsi wrote in his latest book that it was Robert Kennedy himself who fed information to their reporters.
I countered his argument by writing the following :"I am convinced this was not the case. For the simple reason that Henry Luce, the owner and founder of the magazine, was quite anti-Kennedy and anti-Communist. And he felt that Kennedy was not doing enough to liberate Cuba. Luce and his wife Clare Booth Luce were financing the Cuban exiles in their war against Castro and were very critical of Kennedy's failure to do more in that regard. At one point they walked out of a White House dinner after disagreeing with JFK when he tried to convince them to cool it down over Cuba. After the assassination it was C.D. Jackson, publisher of Time, and Luce's personal friend and emissary to the CIA , who purchased the Zapruder film and Life kept it locked up for many years. That way Life was able to control vital information in the film that would have proved conspiracy. To believe that Luce would help the Kennedys destroy LBJ seems a bit unlikely. It would make more sense that conspirators of the assassination used Life to corner and weaken LBJ in order to use him as an accessory to cover up the crime committed in his Texas backyard."
However C.D. Jackson, a Psy-ops expert is one of the most important individuals that i believe was part of the plot and he is probably the person that Charles names as "Thespian". I was suspecting E.H. Hunt as Thespian but now i have settled for Jackson although i could be wrong but i cannot think of anyone else.
I never believed that LBJ initiated organized and executed the assassination but he definetely helped with the cover up and also reversed the US foreign policy.
