Rank is pretty well structured if you ask me, but...
...this is a good idea. Although I think a member is just as important to a clan as it's leaders. The 4 ranks of a clan going: Member, Elder, Co-Leader, Leader; all make sense and work. What i have an issue with are clans who freely give out the ranks and abuse the system if you will. In the sense that, ranks are there for a reason, a reason which it seems hundreds of thousands of people playing the game seem to neglect. I do not necessarily think that adding another rank to the game is going to fix it. But recognizing a members contribution especially to wars is a great idea! Weather it's rank or maybe something to add to their tile. Maybe if a player earns a certain number of stars with a certain clan they can be awarded a star or something that would be worn on their tile in between their name and season donations. This is just my input. Great idea!
