Are 20 war arc Kakashi armed with Zabuza's blade enough to beat Maxed Out Madara in Sage Mode?

So I'm wondering if 20 Kakashi war arc versions, are enough to kill Madara in his sage mode thingy. I do not mean scientific hashirama cell clones or shadow clones or weird duplicates. Imagine 20 actual kakashis with his War arc strength armed with the Executioners Blade. Is he able to kill Madara Uchiha? If not then how many?
