Somehow, Indiana Jones still feels like the most strange proposal of all.
Barring obscure books and such, Indy movies consistently portray animals as obstacles. Indy's most famous quote is about hating a type of animal. I have seen a few people toss around the idea of an Indy-themed snake exhibit, but wouldn't it be a bit contradictory? Indiana Jones movies, for all of their cinematic accomplishments, aren't exactly known for engendering positive feelings/respect toward snakes.
They could try a "Indy tries to conquer his fear of snakes" angle, but I really don't know how that could be done within Indy's adventure serial world.
