Madara's limbo clones can only be damaged by senjutsu or hagoromo's chakra.Apart from the BS plot no jutsu of Black Zetsu stabbing Madara, Madara's limbo clones have been proven very useful in battle.
From what we see in this chapter, Kaguya has shit durability. Got hit by Sakura and shed some blood

Point to be noted, Madara was completely unharmed by Naruto and Sasuke when he had double rinnegan. All the thrashing Madara received from Naruto, Sasuke and Gai was during the period when Madara had 1 rinnegan only
Sakura didn't cause kaguya to bleed, the blood was from the kamui raikiri wound.
If Naruto did something against Kaguya, he'd do it even easier against Madara.Obito stated that if Madara got obtained the other rinnegan, nobody would be able to defeat him

Of course, that was proven false by Kishimoto's usual retarded plot no jutsu, as a mere Black Zetsu was able to physically pierce Madara's body with his bare hands. However, plot no jutsu like doesn't prove that Kaguya is actually stronger than Double Rinnegan Madara. Quite the reverse actually.
Kaguya's dimension shifting is a weak technique and not very effective as offence against opponents. Naruto has hit Kaguya multiple time since Kaguya appeared, which proves Kaguya has shitty reaction time.

This is Naruto, blitzing her for the second time. Without using a distracting technique like reverse harem no jutsu

Not only that he hit her twice, Naruto casually dodged Kaguya's attack.

From the above scans, we can assume that Kaguya is slightly stronger than single rinnegan Madara, because she took less damage from Naruto's attacks. But when Madara obtained his second rinnegan, Naruto and Sasuke were unable to harm Madara physically. Now Kaguya is being spanked by Sakura

I personally dislike Madara after he became juubi jinchuriki and started acting like a clown. But at least he never let himself get hit by fodders. If Kaguya can't react to somebody Sakura, good luck if she wants to beat somebody like Aizen Lol
What a pity
Naruto didn't even attempt to harm double rinnegan madara, they didn't even fight.
