^ No, but that's not really the point. The point is that with the break You get between missions allows the player to look through all available moves and items, reading their descriptions of what they do and perhaps even a little video demonstrating what they look like (a la DMC 4) but not being of any expense to the time it's currently taking You to complete the current mission.
Unless I've taken the OP up wrong, He wants to remove the 'Mission Start/Power Up' screen and simply skip straight to the next mission after the previous missions' cutscene, essentially leaving all the powering up and item purchasing to the in-game Divinity Statues. But again, forcing us to use the Divinity statues would result in a loss of time, which would obviously muck up any chances of receiving an S rank.
As for an Open World environment, that just wouldn't feel right to Me in the slightest, hearing that unforgettable noise every time You press 'Mission Start' accompanied by the screen slowly fading is just as much a needed element of DMC to Me as the Stinger is!
keep up the good work!
