Swamps need a village

I want to see villages in the regular swamps.  Huts up on stilts.  Villagers can access via ladders.  Hostile mobs cannot.  Let's also add swamp specific mobs like herons, minks (give you fur for colder regions if killed), and crocodiles (hostile to players, and preys on other animals)!  Maybe some cattails!  Lastly, I want to see some interaction with swamp witches.  If you don't attack the witch, and feed her cat, she will help you if there is a raid!  You cannot however, tame her cat.
