I don't think that the Maou position is no great honor to being given to Issei because it is a figurehead there is no real power behind the position at all because if the Bael Clan is offering this to Issei he will not just a puppet like Sirzechs is to the Bael Clan now if the position would have imply power then it would mean something, and Issei doesn't want to be like a puppet to this Clan, and his goal is not to become this because politics is a field that Issei would be eaten alive.
