Or someone/something other than a princess.
Yeah that too, like Pauline, King Fret and Prince Pine.

World 5 - Fort 1: Boom Boom (gains wings and flies in the second battle)
World 5 - Fort 2: Boss Sumo Bro
World 5 - Castle: Roy Koopa
World 6 - Fort 1: Reznor (x6)
World 6 - Fort 2: Chief Chilly

The ability to play as Peach from the start and not have her be kidnapped would save NSMB and would make it a whole lot better. Peach could also use customizable outfits and hairstyles kinda like how Roll did in Mega Man Powered Up on PSP except have it be there from the start instead of being DLC. It would also work the same way in Mario Hoops 3 on 3 and Mario Sports Mix.
 
~Unique world themes instead of the standard Grassland, Desert, Beach, Snowfield, Forest, Mountains, Sky and Volcano pattern we've been getting.
~Fresh and original boss designs that aren't the Koopalings. (Sorta like what the first NSMB did.)
~New music that aren't remixes of previous NSMB tunes. (Though if there is at least one NSMB track that I would like to get a remix of, it would definitely be this one.)
~Maybe freshen up the art style a bit?
~Wario and Waluigi taking the places of the Blue and Yellow Toads.
~Maybe include Wart and/or Tatanga as a secret boss?
~Some Sky pop/marine pop stages would be cool.
 
Ooh, on the subject of bosses, why not have bosses in non-fortress/tower/castle/airship levels?
I think they'd work especially well for secret exits.
 
Using music tracks from Super Mario 3D Land and/or Super Mario 3D World would be nice, just to get away from the constant music track repeats.

Desert Overworld

Deep Jungle

Mountain Palace

Snow Overworld

Ghost House

Volcano Overworld

Rising Lava
 
A new villain that isn't Bowser.

That's the biggest lie I've ever told in my life.

I think the Mario series can continue doing without stories.
I think that it would improve levels greatly if they had mini-stories to them that added personality to what might otherwise be a generic left-to-right level.

Not really. I don't play Mario games for their stories. I think they'd benefit more from mini-cutscenes like in Luigi's Mansion: Dark Moon or general character interaction, not any story.
