How does that change the TSB being not that big of a defense boost, unless you're talking about non-Senjutsu attacks. EMS Madara's PS >>> TSB shield in durability. JJ Madara's is leagues above. Thus, I don't see how such an inferior defense could add to Madara's PS tanking ability, assuming the attacks in question have Senjutsu in them, of course. Otherwise it's great for negation.
