Any ideas on porting the Schattenmann (Eisen p120; heroes monsters and villains p57) over to 2e?

For anyone who needs a monster, here's the beaut I'm including in my demo game.  Yes, it is HEAVYLY influenced by the lobstrosities in Stephen King's Dark Tower books.  That and the critters from Attack of the Crab Monsters.  And who can forget the giant crab from The Mysterious Island? Keep in mind, I'm expecting something in the neighborhood of 10 players for this game.
