This thought started off as a bit of a troll idea, but it has some pretty good merit. My 'troll' idea was to make a 'legion of jellies' and it be filled with minis dropping nothing until the last depth. A little exaggerated from LoA.
Enough about that one. After mulling it over a little bit, the thought hit me, why not make a LoA misison to use all the monster families. I think the jelly one could be the easiest to replicate based on LoA.
Just my 45 seconds of actually thinking about it. Oh, if this has already been suggested, just put a link to it and give me instructions on how to graveyard this thread.
