Thinking about Super Mario Maker 2...

I didn't know that the Switch has a touch screen, meaning that the Big N could theoretically do a Super Mario Maker 2. So it's List Time!!


MORE ENEMIES!!
Let me start that list with the most obvious idea. More enemies. We got the most basic Mario Enemies in the Original SMM, well let's bring out some more. I understand that Super Mario 2 (USA) is way different from Normal Super Mario To Make a true blue Super Mario 2 in Super Mario Maker, but the enemies could be brought in and given Normal Mario Properties. Ninjis, Shy Guys, Snifits. then we have enemies from SMB3 that didn't make the cut like Ptooies, alternate Bros. (like fire or boomerang) Buster Beetle. From SMW The Rexes, Dino-Rhinos, or enemies from Super Mario Land like Bombshell Koopas, Pionpis, etc.

-More Sub-Bosses:
Birdo, Reznor, Boom Boom, even Charging Chucks would be a nice addition other than Baby Bowser. The Koopalings (which could work as an alternative to Baby Bowser)

-More Bosses:
Aside Bowser here we could have  Mouser, Clawgrip, Tryclyde, even Wart or Tatanga (which is theoretically a reskinned Baby Bowser on a fiery clown cart) to switch things up. (I so want Totomesu)

-Power Ups:
Superball, Ice Flower, Boomerang, Hammer Bros. Suit come to mind. we could add the acorn suit as well, just to name a few.

-Themes: (Stages, not Look)
We are missing themes like Desert, Overworld at night, Ice Cavern, Lava Cavern. Forest, Chocolate, etc.

-Lava as an obstacle OUTSIDE the castle levels and water outside underwater sections:
Think lava caverns from SMW with the Blaargs and stuff. For the water think of all the levels in SMB3 and SMW that had water and dry sections at the same time.

-World Skins:
We already have SMB, SMB3, SMW, NSMB
How about SMB2, SML, SMW2?

-SLOPES!!! (Both Solid and Semi Solid)
 Do I need to explain this one? These could be used to recreate SMB3 ans SWM style levels or at a more basic level Donkey Kong 25m stage.

-Cannon Pipes: We saw these in SMW they were usually slanted, but having Cannon Pipes would be a fun idea for levels.

-costumes in all modes:
Self-explanatory.

That's just the tip of the iceberg on things I'd like to see... (Play as Luigi or Wario for reals, not a costume mushroom thing would be fun.)
