Using the above as a reference, I'm not sure of the final data storage. The main issue being that you effectively have 6 values that you need to compute (assuming 3D), or 4 values assuming 2D. We could store that as a 6 component Data Array with a known ordering such as +X, -X, +Y, -Y, +Z -Z. We could also output an edge geometry with the misorientation value as an edge array and the let the visualization side of things do its job.
