Hello and welcome to the list, I'm not sure if I completely understand your question but you can certainly read orientations (bone, nulls, etc.) in ICE and you can also drive shape weights. I think it should then be possible to do what you require. Outside of ICE, have you looked at the "Link Deform with Orientation" command? This sits in: Animate > Deform > Shape > Deform Keys. Docs here: http://download.autodesk.com/global/docs/softimage2014/en_us/userguide/index.html?url=files/shape_anim_DeformingaShapeBasedonPosesorOrientation.htm,topicNumber=d28e240340
