No yeah, if Shisui was there, he could use his super genjutsu (i forgot what its called) on obito and madara. So no kaguya, loss of life, ten tails rebirth.....so yeah. Only problem is kabuto, but shisui can just tag team him with sasuke (itachi would still be controlled) and izanami him (as ms isn't required for that)
