Well, the question is clearly shown above. What do you think? I personally wish there would be one.
Unfortunately, the original Super Mario Maker was created for the 30th anniversary of Super Mario Bros. That makes me think that Nintendo wouldn't even think about another until, well, the 50th anniversary (The year 2035 for you math nerds)! Of course, I can always be wrong.
If there were to be one, I'd want a Super Mario 3D Maker. Although it would most likely be difficult to manipulate the landscape, there would be templates based on levels from previous 3D Mario games for you to experiment with before making one of your own. The different game graphics would be 64, Sunshine, Galaxy, and Odyssey. (Also, for manipulating the landscape, something similar to the Landscape Tool from LEGO Worlds would suit the game in my opinion.)
Something new to the game would be different control styles. 64 is only for those who want lower-grade controls, such as less traction and wall-jumps are harder to perform. Punching and kicking are also part of this style. Sunshine controls add F.L.U.D.D. and Mario is unable to crouch. Galaxy controls are the same as Super Mario 64 aside from the special spin jump and easier wall-jumps (Same with Sunshine). Odyssey controls add the awesome hat throw mechanics and, for some enemies, Mario can use Cappy to capture. New textures and animations will have to be created, of course, for Cappy and captured enemies in different graphics; same with F.L.U.D.D. of course.
