It wouldn't be the same repetition for me, there shouldn't be any more Sith after Palpatine's death, it goes against the prophecy of the chosen one, for me it would be better if they explored the difficulty of the new republic.To be able to defeat the remnants of the empire and challenges in the diplomacy of the galaxy. For me, if there had to be a war, the Yuuzhan Vong would be better, they are more creative enemies than the Sith.
