Lumeris - Sleep With the Fishes

The Lumeris are presented as aquatic mafia families with a penchant for real estate development.  How could there not be a mission where someone is "Sleeping with the fishes?"  

Maybe there is a reference that I haven't seen yet, buf if there is not, then I strongly suggest your expert writers should write one up.
