It would be interesting to have a Captain who didn't feel the necessity to mince words and speak through a "PC" filter.
The Star Trek property answers only to a master that sees characters in one way; in other words, TPB would not have the interest--or the balls to ever have a character like Archie Bunker as captain (no matter how much of an interesting, potentially groundbreaking change that would bring to a stale property), and not make him a villain all others must foil in every story.
