Having a character as both ruler and general would limit the amount of people in council positions, rather then expand the number of people in council.
Most realms where I had a leadership position formed their own ruling council anyway, I rarely see the game-mechanic council being used.
But, yes, I don't oppose the idea of renaming marshal as generals and including them in the council. I just think that, if that is the case, an overseer position over all generals (War Minister?) should be retained, and not forcibly merged with the ruler.
