That would be cool. The feasibility depends on how they implemented it in the engine. It might not check the state of the player, just slap a fixed "CMDR " string in front of your name. So it might be difficult for them to write an optimized way of reading the player's ranks, then showing them. I also remember Devs mentioning that you are not supposed to be super-important in the game. Might be that they don't want to make a player own a station, outpost or capital ship, because literally it is beyond your class or rank in society.
