Well with Kaguya, he will be able to continue story , show some new otsutsuki , make a decent opponent for Naruto and Sasuke.

Lets be real, they had more screen time then Madara did + they also use to handle him just fine , and if touch in same time is everything that it takes to defeat him , well then he ain't much of a opponent for two of them.

He also lack some of the abilities to fight them at the same time. We really haven't seen much from TTJ Madara so who knows when did even kishi made his mind to make him a vessel.

And yet only reliable thing that Kishi came up with to save Madara is switching places with his Limbo clone. Well he do need more of those abilities, then he might be some challenge. Otherwise he gets crushed like nothing.

Anyway there is also one thing that he gains with Kaguya revival. After casting IT he came confident to kill them both, in other words if Sakura or Kakashi would try to stand in way , he would simply Kill them or use them to distract Naruto.

So i believe with Kaguya he was able to spare those two, and also to lead story line on Kaguya origins.
