I think a rollback won't be possible considering all battle results and random events involved in a turn. Imagine your 25MR SC dying to a single desintegrate spell or a nasty death event in your capitol after a rollback and that nothing like that happened before the rollback...
And I am not even talking of players changing their order on the strategic map or battelfield now that they can predict the move of their opponents.
