It'd much easier to use a second Transform as a MatrixTransform, then just get the matrix from the first PositionAttitudeTransform and invert it. However, perhaps just fixing the scene graph so that you don't nest components the way you have, the fact you are needing to do this screams out to me that your scene graph is inappropriately structured, and you should move the nested subgraph out to be a sibling of the upper PAT.
