multiple rank images/usergroup hierarchy

[Stray]

Is there anything that allows multiple rank images available?
I want to allow users to have a custom title and multiple ranks. For example, if I had a mod who was also a clan leader, he'd be in the mod group, the clan group and the clan leader group. I'd like to have his custom title, an image that shows he's a mod, an image that shows he's in a clan usergroup and then an image showing that's he's a clan leader.
Currently I think the custom title wipes out the primary usergroup rank and you can only have one secondary usergroup image.

I also mentioned in another thread that I think a usergroup hierarchy hack would be very useful for a variety of topic related boards, although I don't know if it's possible or exactly how painfully difficult it might be. Something that shows users ranks within the usergroup might be very popular, especially on gaming forums inhabited by multiple clans.
