Well, no, because I just don't think you need game mechanics to play a "leader" character. That's something that should be roleplayed.
And realistically, if you let someone who doesn't have real world leadership skills try to play a character that does boss others around, it's really not going to work well - lots and bickering and such.
Obviously you're not a player of 4e. You'd be amazed at how well player characters fall into line following a character's lead when he gives them bonuses to attack/damage/saves/hp to obey.
That's why the Warlord has such affection among 4e players. It takes what should be an obnoxious premise, and it works.
