I won't be arguing about Sasuke's one, but Madara's words proved he'd used his PS with the EMS, even if it wasn't shown in the manga, wich means that EMS-Sasuke could do it either. Agreed. His statements make little sense if he developed it afterwards.

Considering what Perfect Susanoo is -mostly just a far bigger Susanoo- and what Majestic Attire is -a far bigger Susanoo suited for a Biju- i would expect PS to be at worst just a leg up from Majestic Attire, and very achievable for EMS Sasuke, even if he didn't get the chance to show it.
