Edit: I totally missed the point of the thread, the post still stands though.
Assuming you want a MT/OT group. I think these two specs would do pretty well together:
MT:

OT:
http://www.wowhead.com/?talent=TVZVx0VZcAtobMd0ekt
Within the group this would give 5/5 Commanding Presence, 3/3 Imp Thunder Clap and 5/5 Imp Demo Shout while maintaining 41 points in Prot for devastate for both MT and OT.
