What you are proposing would work if we had a system like Star Wars Galaxies "Famous NPCs", but since President Powell exists in-game only in news reports, it cannot work viably and denies the use of a major character (think of the possibility of in game assassination attempts, diplomatic meetings, interaction with Gottkanzler Rheinhardt).
The Freelancer AI engine is not advanced enough to support truly intelligent and vibrant NPCs. Thus, players need to step in to (if you want major roles to function actively in game) take major roles, since they are the only ones who can fulfill them. Though, as a matter of interest, Niklaus Rheinhardt is no longer an in game character. He does exist on the forums, however.
Though, as I've said, it depends on whether you think the role of Powell is needed or wanted. This is mostly hypothetical, not a demand for implemenation.
If you want the RM to completely alter themselves, that's between you and Virus. Also, where exactly are you getting this idea that the RM want to ban independents of every faction? I've never heard anything from anyone in the RM that would support such a thing.
What I'd propose is creating a joint forums account called "James Powell". Have the login available to an administrator or admin-approved individual and have each post reviewed and scrutinized by the admins, to set things ahead in a DM/GM-like manner.
