Is there just one leader in a company? We have an old linkshell getting together and there is some friction between a couple of people on who should be the leader. It would be ideal if there were four people or so in charge.
Key thing is there's always going to be one player who's technically "in charge" of the whole shebang. However you want to set it up after that is up to you, but the existence of one (and only one) guildmaster is a technical limitation.
If random outcomes aren't acceptable to you, then don't play with random people.
