[Bf-python] Bf-python Digest, Vol 38, Issue 2

[Campbell Barton]

You could do this in blender by importing the bvh twice, modify the 
hierarchy of 1 and then constrain the bones that have altered motion to 
the original armature.

However, there is no exporter for BVH, but you could export to FBX, and 
convert to BVH with some other app.
