EMS unlocking PS is pretty debatable. I mean the manga showed 4 PS users(Indra, Madara, Sasuke and Kakashi) and what combines all of them is Six Paths Chakra(Indra was said to born with "sage's[Hagoromo's] eyes, spiritual energy and powerful chakra", most likely meaning some form of Six Paths Chakra, Madara got it by implanting Hashirama's DNA into himself[awakening Rinnegan in the process], Sasuke got it straight from Hagoromo[as well as Rinnegan] and Kakashi got it from Obito[who got it earlier by stealing it from Madara]). And while Madara's statement during the Gokage fight could be interpreted that he could use PS with EMS alone, Hashirama's flashback doesn't really support it... Or at very least, Madara(as well as Sasuke with Naruto against TTJ-Obito) could do sort of-PS by using MA: Susanoo with Kurama, since Kurama's chakra can enhance ninjutsu(which Susanoo is).

As for that NS episode that showed Madara using PS through EMS alone without Kurama, that was only in anime and anime-only stuff are about as canon as Rock Lee-spinoff, so that should be taken with a grain of salt.

That said, to the question, "can PS be used through EMS alone?", I'm going with big maybe. I'm not saying it's impossible, just that it isn't 100% definite either.

As for the topic... hard to say, but it would be interesting fight.
