I would like to be able to have a character who is running, get chopped up and have the pieces continue forward with the same momentum the character had. Also a variety of dismemberment would be nice. Any ideas?

3I found a script i the asset store: Piecemaker Mesh Destruction, I didn’t try it, but it could be possibly what you are looking for.
The easy way:
Your character should already be a ‘sleeping ragdoll’ - complete with rigidbodies and motion-tracking (so your code knows how fast each rb is moving/rotating). When it gets chopped up, enable all the rigidbodies and disable animation and it’ll fall like it should.
For each piece you want to cut off, create a prefab at the bone’s location & rotation, then scale the bone to zero relative to its parent (.localScale = Vector3.zero) and move it directly to its parent (.position = parent.position). Give the prefab the velocity you’ve been tracking and it looks pretty reasonable.
The hard way:
It’s finally possible to slice skinned meshes (see SkinnedMeshRenderer.BakeMesh in the script reference): here’s my one-day test. With only ~4700 vertices, it’s a several-second pause to do the cut, but coroutines could potentially hide that.
You can use existing asset to do it: Unity Asset Store - The Best Assets for Game Making

Anything is possible if you're good enough at programming. That particular task is very difficult to do well, which is why it's not in every second game..
