I think the First tried that against the Third.
But I agree about Madara. Even if he had a plan at that point, it wouldn't rely on Sharingan manipulation. Why bother? The ninja world was full of people getting murdered and the desire for revenge. He would just have to wait for the right person (like, how Obito waited for Nagato).
Random question time: is spiral Zetsu the same as "black" Zetsu? How did Obito "give" Nagato the Rinnegan? It didn't look like he did a quick surgery on him while the mist or whatever attacked him.
