There are ragdolls for iClone 5, using Bullet physics.
Wil Veeke, I believe, has done things with dummies attached to characters, to get anti-collision behavior. That would be the basis for a physics-based ragdoll.
There is a lot of machinery available in iClone that allows you to do things (sometimes in an unusual way), but it may not be ready-made. Perhaps once scripting becomes available, developers will become creative based on demand.
